I show you what happens when you drop a magnet near cold aluminum See the full video here: • Giant Monster Neodymiu... Subscribe to my main channel here: / theactionlab #shorts
Lol I wanna see the blister he got from that. Us Canadians don't mess around with cold cuz we know it's as bad as hot, or worse. The pain from frostbite is worse than a burn of the same level because it bursts the cells rather than denature them Him saying "ow" at the end of the video is from ice crystals shooting through the tips of his finger essentially stabbing the pain receptors I could be a little bit off but know that frostbite is quite painful from experience
The scientific way. Have a bunch of rules, protocols, and previous incidents as examples. Then ignore most/all of them. Lowkey, science is more fun with danger involved.
Google: "The vapor of liquid nitrogen can rapidly freeze skin tissue and eye fluid, resulting in cold burns, frostbite, and permanent eye damage even by brief exposure." This guy: -Cold Cold ....... Ouch
That cold handling “ouch” reminded me of an extremely stupid radio d.j. who held a competition here in the u.k. (2003)to see who could sit on a bock of DRY ICE 😳🥶 the longest. Of course the first thing to happen was numbness so they didn’t know that they were being burned. Four contestants were taken off in ambulances and hospitalised for months with severe burns which needed skin grafts. One doctor said that if it had been on their hands or feet there would’ve been amputations.
DJs should really consult doctors before running their competitions. Between the dry ice and the "Hold your wee for a Wii" guys, I'm convinced that DJs are agents of chaos.
yeah its crazy, a changing magnetic field creates a voltage by faraday's law and that voltage produces a current and that current which is a movement of changed particles creates a magnetic field which is in opposite direction to the movement of the ball from lenz's law.
Normal kid playing with clay and toy car Action lab kid be like: Mommy I want to make a toy, Do you know where I can find liquid nitrogen and aluminium at -200C??
Yes silver is the best conductor Only reason why people think gold is because all the plating on contacts of stuff but that reason is because gold doesn't oxidize But technically pure silver doesn't either but pure silver is too soft and easily damaged Just fyi copper is better than gold as a conductor gold is 75% of copper in that department
I have learnt so many new things from this channel and the other one. I love science experiments not the theories that I should remember. And in this video I learnt that when the metal is too cold, the person will scream the same way when the metal is hot but the word will change from hot to cold xD
I like how he's showing us blatantly obvious stuff like how the metal ball drops instantly when by itself, but then he doesn't put on gloves when handling something cold asf. It's like, ahh yes man was once monke indeed
@@douglasharley2440 I'm grateful you commented I am very curious about super conductors I've been experimenting with them a lot lately. Do you mind explaining what's happening in this video in detail?? The science behind I mean, why does it slow so much and act differently under different temperatures? Thanks in advance
Yeah it's cool !! Technically if every mechanism has a timer or a clock and that clock slows down it kinda is slowing down time it at least for whatever's happening
@@sethlt9681 watch it again...the passage is slowed because of magnetic eddy currents induced in the surrounding material, and the speed changes due to material changes in conductivity due to temperature (as temperature decreases conductivity increases, thus the eddy currents will increase, increasing the magnetic "drag"). lol, if you've seriously been experimenting with superconductors i find it difficult to believe you do not understand the very simple physical principles involved in the demo here.
So I've known about those toys for a while, and I only recently did research on them. So if you want to know how it works, read on This is due to a property known as Lenz's Law, basically, a current creates a magnetic field (like how an electromagnet works), and a changing magnetic field creates a current (this is those "eddy currents" he was talking about). When you drop the ball (a magnet) through the tube (a conductive metal that is not magnetic), it's creating a current. The current is then creating another magnetic field that is opposing the magnet, slowing it down.
ouch... bet that hurt a tad, good thing your finger didnt stick to it like the tounge on the frozen pole trick... I knew it got slower when cold but didnt think it got THAT slow..... wonder what neat kind of stuff you can do with a spherical magnet...
For a fun toy to play with, get two of them, and if you really want to have a good time kids, bust out your personal storage of liquid nitrogen to douse the toys with. Remember, not wearing protection makes things even more exciting! - Action Lab
Well it works according to Lenz's law of induced electric field due to change in magnetic field lines passing through the conductor due to moving conductor or changing/ variable magnetic field
cold burns are quite strange. the pain comes way slower than heat, it actually feels like a typical heat burn, but it's way more area affected than you see,which is just red skin,way deeper that start stinging and while it's not (yet) a great pain, the myriad of needles inside the burn still feels eerily life altering. warming it up gives the sensation of being crushed in a bench vise, but vise versa, like it crushes you from inside out. but watching/feeling the solid n2o (-88°C) sublime with unbelievable force under your finger is just spectacular. luckily no permanent damage, but the whole hand was fucked from a rather small affected area for like 2 days. skin got really dry afterwards leaving the reign of everyday physical conditions is so refreshingly mind boggling
