"many people think it's there to seal the bottle properly...well not exactly, it's actually there to prevent the gases from excaping"...so in other words it's there to seal it properly😂😂😂
LOL...Right!!! Oh and I love the one with the glasses. I kept waiting for him to tell me something I didn't know... After he moved on to the next one all I thought was 'You've got to be kidding me! Do people really not know that???'
Anyone who uses a utility knife enough to know there's lines on it is probably well aware of there purpose....and anyone who isn't probably didn't even know they had lines to begin with😂
Well...only one of the four knives he showed had that kind of blade. The utility blades that are trapezoidal only have side "ends" and are NOT meant to be broken at the scoring marks.
it actually hurt me to listen to the guy explain why we need to have arms on glasses, it made me almost mad to be told why there are lines one the blades of utility knives... thank you so much captain obvious :p
They probably think its some kind of bluetooth black magic that they dont understand so they just throw it away instead of sounding stupid and calling customer support :p
For your next video on this subject, might I suggest the following? -The pointy end of the screwdriver is the correct one -Pouring liquid into the OPEN end of the container works better -Looking out of the window instead of staring at the wall makes it easier to see outdoors -The holes in the ends of scissor handles are for your fingers -If you are moving yourself about by slithering like a snake, use your feet and legs, it's easier -The sharp side of the knife is more effective at cutting -Eating soup or cereal from a bowl with a spoon instead of from a plate with a fork works better -Open the door BEFORE walking through it!
You had it right with the break-off blades, but then showed utility blades that aren't meant to break-off. I'd hate to see someone trying to break the blades that are not meant to break. One word: LIABILITY
Skip Yo and anyone who's had glasses has most likely had one (or both) of the arms break off at some point so like if people didn't know before they would know after.😂😂
Michael Kuck same here and I use the term on an almost daily basis...so I am looking forward to people's reactions when I start calling it the earth wire.
Not even 20 seconds in and you suggest *we" don't know what the slanted scores (there actually more vertical than horizontal) on box cutter blades are for? -seriously?
Once Upon A Potato No, he said, "people think the colors tell how much chemicals are in the toothpaste" I am saying that they are completely full of chemicals. Besides the grammar of that sentence is horrendous.
Eric Taylor Neutron stars and black holes are not made of chemicals. They are so compressed by their own gravity that it is impossible to support any kind of atomic structure to form elements. Without elements, you have no chemicals. It also goes without saying that discrete subatomic particles are not chemicals, either.
I had always heard it referred to as a "ground". I again saw the term "ground" come up when it came to working on computers and I assumed the meaning referred to some kind of discharging (as is the case with computer maintenance).
Vincent Hirche Here I live (Norway) which is we are following the EU standards for plugs (2 prongs) and I still know about what the 3rd prong is about. But ofc the plugs in eu also have grounding.
Here in the uk the earth pin a plug has another safety feature. When plugged in the longer earth plug opens the safety cap for the smaller 2 prongs to prevent shock
+Disney Lover it's not a myth, it's a british standard requirement. It stops kids sticking stuff in live sockets. If you were shocked it was probably down to using a damaged plug.
I love the one with the glasses. I kept waiting for him to tell me something I didn't know... After he moved on to the next one all I thought was 'You've got to be kidding me! Do people really not know that???'
lol. At the 1st one.. not all razor blades have that line to break it at.. people cannot be that stupid when they see a razor blade that is 4 inches long with lines going through it.. and yes people didn't know they did that.. well at least most people
for example and my point.. At 0.20 that box cutter does not have the lines on the razor blade to break it off.. so why in the world would you put that in the images? that razor blade does not apply
+theBald1 last one on my point with razor blades.. And the same applies for the one at minute marker 0.32.. they will not break at any line because the line does not exist on these blades
Actually, because dimes and coins of higher denominations were originally made of silver and gold (unlike today!), smooth edges on those coins made it easy for criminals steal some of the precious metal without it being noticeable by shaving it off (called "clipping)*. Making those coins with reeded edges was intended to make any such tampering immediately obvious. The edges on pennies and nickels aren't now, nor were they ever, reeded - shaving their edges simply wasn't worth the trouble. The main reason modern coins are produced with reeded edges? Tradition! *This didn't make them worthless but did reduce their value.
It is true in times of old coins were made of gold or silver & ppl would shave the edges to sell the accumulated gold but it didn't make them worthless he didn't explain it very well huh
Mawsy 1980 I wouldn't even go as far as saying "in times of old" In 1966 Australia minted a "round" 50c coin made of 80% silver 20% copper. Jewish businessmen at the time were collecting them by the bag full and sending them back to Israel to making profit from melting them down. Because the scrap value of the metal grew to be higher than the face value of the coin they were replaced by the dodecagonal coin in 1969.
It's ur voice seriously??? If yes, then mann hats off to you!!! I always thought it's a computer's voice (like ivrs when u daily to customer care) U r a real Champ!! 👍👍👏👏
but there not an everyday use item , people are lucky to use or see them at least once in there lifetime and would have to do searches to see if there real or not
Iluvthings Yes I'm a real person see you have never heard of them thats why his video wont work very well , people will think its fake and dislike it to much
Anyone else remember having that hard tracing paper stuff as toilet roll at school? it would scratch you to bits and was impossible to wipe yourself clean lol
Are you trying to tell me that somebody out there doesn't know why glasses have arms??? If they can't figure that out I can't imagine they would be able to use the internet to somehow get to this video.
I was relatively proud of myself, considering I've never actually used box cutters firsthand. I've been around others who use them for work or crafts but hadn't needed them personally haha Glad I learned about it before I potentially wasted money to replace a blade.
#1. Most disposible blades have a slot in the end to insert the blade and snap it off in case you dont have plyers (better tip than "you can break off the tip") #4. The holes in the prong are meant for child safety, insert a keyring in the hole and prevent children from plugging in the appliance
The lines on the box cutter are only horizontal if you hold them parallel to the horizon. You mean diagonal. What have the other three knives you show to do with a box cutter with a snapable blade? What's the difference between keeping the liquid contents and the gaseous contents of a "soda" bottle inside? Answer: none. Wall socket consists ONLY of a power outlet. The plug is purely optional. One pin is live and the other is neutral. It has nothing to do with passing "unused" energy. If that were so, you wouldn't need it. What has the picture of the Rouble coin to with an earth connection? What have the plastic "Croc" shoes to do with fabric "Converse" sneakers? What does a picture of someone putting essential oil onto the core of a roll of toilet paper to do with the quilting of the paper? The quilting is not designed for its abrasive qualities. Its purpose is to hold the layers together. If you've ever worn spectacles, you'll know that the shape of the ends of the arms are designed to grip your head, not your ears which would be uncomfortable. Completely straight arms that curve inwards at the ends are quite practical. Coins have been found in the Indus Valley civilisations dating to 2500BCE. Touching a coin will not reveal if it's fake or not. If that were the case, there would not be £600 million worth of pound coins circulating in the UK would. You have to examine the coin carefully to detect a fake. This is not a problem as long as everyone accepts the coins as being worth a notional £1. The milling on the edge is to prevent "clipping", not "scratching". Isaac Newton, when master of the Royal Mint was particularly ferocious in his pursuit of these "coiners". You present a lot of dubious assertions as fact. In fact it's just another load of dog vomit. Thumbs down.
+dragonvale19 I disagree with your fucking comment. This film is entitle "8 Things you Didn't Know..." which is entirely correct. There are a lot of things in it that I didn't know, because they're not fucking true. The poster sets himself up as source of information but fails miserably in the endeavour. He (because it's certainly a man) thoroughly deserves to be hauled across the coals for peddling such bilge.
1st thing : parent works at B&M and has one, also common sense 2nd thing: i'm pretty sure that's the seal, or something not in the uk 3rd thing : ok, you got me... 4th thing : uhh, no.... just no it's to open the socket for the rods.... don't believe me? get a spare cable and snap the top bit off and see if it will let you plug it in...
oops. 5th thing : I knew that, but you were finally right 6th thing : second thing I actually didn't know 7th thing : a bit obvious..... 8th thing : I think you might actually be right... (3 / 8)
HG 22 I was always under the impression that the markings on coins were for blind people to differentiate between the coins...all the markings on all the coins are different for this reason
wow that was a waste of 7 minuets. other than the markings on the toothpaste (which I don't expect anyone who hasn't worked in manufacturing to know) all of this is common knowledge
The last one there is another reason.. So blind people know witch kind of coin it is such as 5c 10c 20c 50c $1 $2 that's why they have different patterns on each coin value, well in Australia anyway
Most people think a chair is a defensive weapon to be used in event of alligator attack, but did you know it's original use was to keep your ass off the floor?
Things you forgot to mention... Why aeroplanes have wings. Why cars have wheels. What the prongs on a fork are used for. What the handle on a door is used for.
The plastic disc on a bottle top is a security device, it shows that the top has not been tampered with, virtually all bottles and jars have the same device.
Your explanation of electricity is abhorrent. Both pins (active and neutral) serve to transfer the energy into the device. One doesn't put it in while the other takes away the excess. They are both used to complete the circuit. And no, Earth pins aren't typically round. It will vary depending on where you are.
Yeah, these people should avoid explaining things they don't understand. Opposites attract. One prong connects to current. the other connects to neutral (opposite of current. This is not negative, just neutral. A/C has no negative load. The neutral is connected to the center of the transformer which supplies voltage. All neutral wires are hot until they are bonded (essentially grounded). The ground or earth prong will not prevent the device from overloading. It is there to protect the user. It is attached to the metal parts of the device which are not intended to conduct current, especially the pieces the user might come into contact with. Even voltage from an electromagnetic field can shock a person, but it will always follow the path of least resistance to the earth (or ground). The human body has a very high resistance to electricity (a poor conductor of electricity.) Therefore a ground wire, being a good electrical conductor (low resistance) will take all current to ground (on household devices). If enough current travels directly to ground with (virtually) no resistance, a breaker or fuse will trip or burn out. In cases of high current, a ground wire that is to small will not provide sufficient protection.
Your explanation is not quite correct. Although I do basically agree with it. Yes, A/C does have a possible negative, and that would be the other hot wire, in a 240-volt circuit, well at least in typical residential U.S. wiring. (I think it is done differently in 230-volt 50 hertz countries.) They are 180 degrees out-of-phase. Is that negative enough for you? In fact, I saw in a electrical wiring book, a description of how a 240-volt circuit can be run to receptacles in a kitchen, so that with just one wire cable, 2 separate 20-amp circuits can be supplied. One hot wire supplies one circuit, and the other hot supplies the other circuit. The one neutral is shared, and only has to carry the difference in the currents of the two circuits, and serves to keep the circuits balanced at 120 volts. One ground would also be shared. The wiring cable used for this double circuit, would be 12-guage 3 conductor + ground, I think. It would be connected to 2 separate 120-volt circuit breakers, I think, from opposite 240-volt sides of the power bus in the circuit breaker box. However, the negative is not negative in the sense of DC wiring, as A/C reverses and travels in both directions. A 240-volt clothes dryer plug would have both hot prongs on it, and if an older plug, a shared neutral/ground. If a newer dryer cord, it would have 4 prongs, 2 hots, a neutral, and a ground. Neutral is generally grounded, however, the ground typically would be at the circuit breaker box, and since the neutral carries current, it can have up to a few volts on it, relative to ground. Because long wires have resistance, especially at high current loads, there can be some voltage drop, or in the case of a neutral, is can be a few volts above that of ground. The ground is not supposed to carry current, unless it has to, to help remedy an electrical fault or shock hazard.
Yosef MacGruber, You are thinking of a single phase 240 volt system as one sinewave. The transformer which supplies the voltage has a center tap on both the primary and the secondary side. These 2 center taps are directly connected, then grounded. That is what provides the opposite required for attraction. A single winding cannot be out of phase with itself, and if the two legs were 180 degrees apart, the voltage between them would be zero. If you draw a complete sine wave, hold it up to a mirror (with the zero line parallel to the mirror), your drawing would represent one 120volt buss in your breaker panel. The point where your drawing meets the mirror would represent the neutral. The reflected image would represent the other 120volt buss in your panel. You'll see that they are in phase but opposite, that is, when one is at +120v, the other is at -120v. But they are on two separate waves, so they are not 180 degrees apart. Frequency is the rate of occurrence. Hertz is a unit of frequency. In the USA, each of those 2 complete, opposite sine waves occurs 60 times per second. Either wave measured back to the center of the secondary winding will read 120v. When measured from one end of the secondary to the other, we get 240v. when we connect the center of the secondary winding to the center of the primary and ground them, the result is 2 separate, opposite waves in sync. Since they are opposite, at any given time, one wave is at +120v and the other is at -120v which gives us the full 240 volts. But since 120 is only measure to the grounded center tap, when leg is +120, the other is at -120. The reason a 240 volt circuit can be split and share one neutral is at any given time, only one buss in the panel is hot, meaning the neutral only serves one 120 volt circuit at a time. The reason the other is not a true negative is that 60 times per second, the negative becomes positive and the positive becomes negative. If a single neutral is shared between 2 branch circuits loaded to their potential on the same buss, the result will be an overloaded neutral. (potential=85% of the wire's current rating is maximum standard since 100% would be right at the point of tripping a breaker.)
Steve White Technically it would be 2 phase, 120 V AC. You don't need the ground connector. Lots of power transmission occurs in a delta configuration, with just 3 active lines, with no ground. Each is 120 degrees out of phase. A single phase will ALWAYS have the 2 ends out of phase with one another, or be at 0 V. That is because while one side is positive, the other side has to be negative. If the 2 legs were in phase, the voltage between them would be 0, or a simple DC voltage. The easiest way to explain that is to consider 2 sine waves. When they are in phase, they overlap, or have a simple offset. The voltage between them is fixed, and without a DC offset, it would be 0. If they are out of phase, then the voltage between them differs. If they are 180 degrees out of phase, the voltage difference will peak at 90 degrees and 270 degrees being 2 times the amplitude. Being "in phase but opposite" means they are 180 degrees out of phase. You also seem completely ingorant of how electricity works. For AC, the hot wire is the one which isn't grounded. It is the one that can kill people. The ground one (assuming the hot one is disconnected, such as when it is switched off), by virtue of being grounded, will always be at 0V wrt ground and thus if you touch that one, while you are grounded (such as by standing on the ground or something that is grounded), there is no potential between you and the neutral line and thus no current would flow. The active or hot wire, while having a very short time at 0V, will otherwise have a potential wrt ground, and thus want to use you to complete a circuit if you touch it and the neutral one is disconnected. It doesn't matter if the potential is positive or negative. It is still hot. A typical 2 phase AC circuit will not use the neutral at all. This is because it is 2 phase because it requires more voltage/power. If it could act as 2 devices each using the neutral then there would be no need for 240V. But yes, a 2 phase AC circuit with a common ground, can be split into 2 1 phase circuits.
Steve White To eleaborate a bit more, typical 3 phase AC power can exist in 2 configurations, a delta configuration or a Y configuration. The delta configuration has no ground. It only has the 3 hot wires. The transformers/generators/motors/etc are wired up as 3 coils between the 3 hot connections, in a triangle. The Y configuration has a common ground. This would have the 3 coils run between the ground and each hot connection, in a Y shape. If the 3 phases are balanced such that they all draw the same power, the ground doesn't take any load at all, as it sums to 0. Regardless of which way you do it, they are 120 degrees out of phase. For a 2 phase system, it would basically be the same, but instead of a Y you would get a center tap coil, or 2 coils connected, and instead of a delta, you just have a single coil. The pseudo delta, with just a single coil could be considered just a single phase, as there is no reference point. However, it could also be considered as 2 phases. As the centre tap/2 coils actually has a ground, it would be more correct to refer to that one as 2 phases, especially as you can get just one phase and draw power from that while ignoring the other phase. Also, you want the breaker to trip before the maximum current rating of the wire, otherwise you risk having the wire melt instead of the breaker tripping.
"A tissue paper stick to us and not clean us" and then u need other to clean urself.. 😁 lol.. In India we here use water, i think that's better than using a tissue.
But you flush toilet with water, so why is it parasite infested shitty water in India and not everywhere if we all flush the toilet? It has to do with filters or the lack of filtering systems that cause health hazards.
King Kush lol... Its not like we r drinking direct from river!! In my house we drink *boiled* water. And every other house has water purifier.. # misperception.
***** Hehe it's not like other people having drain pipe in their houses. Its first go to water treatment plant and then we also boil or purify that drinking water. U should stop using petrol/diesel as its causes air pollution. Its just the reason u give is not valid.
there's a lot of commentary here that is unnecessary. This video could be shortened my cutting the script that has nothing to do with the issue brought forth.. Pointing out the obvious does not educate, it just wastes our time.
But if they cut out the stuff that was already common knowledge they would have to change the title to '2 things you didn't know about everyday objects'. The converse one and the colored marker on tooth paste are the only 2 that most people wouldn't know. Even then it would be more from people not caring than from misconceptions. This was so poorly done that I am surprised he didn't mention that the holes in pot/pan handles is supposed to be a spoon rest instead of being there to hang it up when not in use.
1: new it already 2: new it already 3: new it already 4: something new 5: new it already 6: yep I heard it when I was 5 7: yes a WEAR glasses 8: new it already
+Alex Baker.... I also can tell you something you didn't know.. that English is not my 1st language nor 2nd... so I bet that I can word sentences at your language than you at any other.. tks
Bruno Pereira then use your own language then your fucking melon because you can't use English correctly you fucktard and I couldn't give a shit if you can use other languages better than me because I'm English and don't care about talking French or German or Spanish because I don't "wait for it" give a shit !
Oh my god! You two are so pathetic, it hilarious. You claim to not care what they think, yet you care enough to comment about how much you don't care. Oh, the irony.
Steven Walker They may be "almost perfectly synonymous" in conversation but Americans use the term "ground" in the electrical sense unless the wire is actually getting stuck into the dirt.
okay, quick survey: did you know, before watching this video, that the arms of glasses were to keep the glasses on your face thumbs up for yes down for no
Ehh number 4 i tink it just beacus i study that end i leard that the first year on middel school but i feld like a geaneus when hering that ( sorry for my englich i 'm dutch )
Why would anyone ever question why eyeglasses have 'arms'? Next thing I know you're going to tell us a doorknob is there to help you open the door......Oh wait.
The most surprising part of this video was that a notable segment of the population thinks that the colored marks on tooth paste first of all implies how many "chemicals" are in it, and secondly don't bother to use the computer they call a smartphone and learn what the word chemical means.
I've watch a couple of these now, and my theory is that they are created in India. The script has a lot of British terms and awkward phrasing, but they get an American voiceover artist to read it. The subjects are often obvious to anyone who has grown up in a fully industrialized country, and the images are taken from a Google image search for whatever words are being spoken at that moment, without regard for the actual topic. They literally just googled "shoes with holes" and put random pictures in because the person doing that part doesn't have any knowledge of Converse All-Stars. (They used the correct picture only when those words are actually spoken.) Likewise, the utility knife blades shown don't all have break lines. The bottles aren't all screw-top fizzy drinks; and so on.
Sorry, but 6 is wrong: toilet paper are quilted to increase the volume of the roll. Non-quilted paper wipes just as fine. (The wiping properties has to do with surface structure on µm-level)
Glasses consist of nosepads, nosepieces, eyewire, endpieces, temples, and temple covers. As an optician I hate hearing them called arms. The reason behind them is pretty much common sense though.
Pretty sure the reason why modern coins have special edges is to allow blind or low-sighted people to verify their denomination. A U.S. nickel and a U.S. quarter can feel very similar in size, but a quarter has ridges on its edge, while a nickel's edge has a smooth finish. Same thing with pennies and dimes.
The only one I didn't know was the toothpaste one, but I don't work at a toothpaste factory either. "Many people think this helps close the bottle properly. Well not exactly. The plastic disc is there to keep the soda from going flat." by enabling the cap to close properly on the bottle.
one toothpaste manufacturer I know of has a secondary use for the markings: the precise location (left, right, middle) tells what tube-manufacturing-line it comes from in case a batch turns out leaky.
