I was born in the early 80s, but somehow managed to completely miss out on this show, until I discovered it on RU-vid. I would've loved this as a kid, and will happily show these clips to my son when he's old enough.
I read on Facebook about an elderly couple who contacted the police regarding someone siphoning their camper van using the suction method. The couple heard a strange noise during the night which he didn't investigate. On exiting his van he found a siphon hose vomit and the cap to their camper vans sewage tank. During the night the thief mistakenly siphoned their sewage instead of their petrol.
A RU-vid video taken by a hidden camera of that event would have over a million hits! Surprise no one has faked it - Oh I think the News Networks are busy with other fake news
Dear CuriosityShow, I just want to say: Thank you. I watched your show in Germany in the early 90s as a child and it sparked my interest in science. Now I work as a scientist and recently I remembered that one show I saw as a child with that cool experiments and tricks. It's incredible how it inspired me and surely others too. Thank you for your great work.
It was a great show, should be on the air today here in Australia. Our children would be better educated and would have more constructive and interesting projects to get involved in.
@@arconeagain theres more money to be made by showing children cartoons, then selling toy characters from that cartoon. education cant compete with profit
@@hindugoat2302 yes this is too true. However, we have a thing called the Australian Broadcasting Corporation, a government, tax payer funded television channel/s. They have several kids channels and programming. They also play re runs and can acquire the rights to air certain programs. In saying that, I am not happy with the ABC. They have basically become a commercial channel, they endorse Facebook, Twitter and such. This is apparently accepted under the legislation, a bit of a loophole. They're meant to be completely independent of any kind of profiteering, commercial endorsement or bias.
Another clever way to do this with a regular hose, is to dip the hose much further into the source than you need, plug the exit end of the hose well enough to be airtight, then pull enough of the hose out of the source that the liquid has made it well over the arch, then you may release the airtight hold you have on the exit end, and gravity does the rest. If you have any trouble with it, just pull more of the hose out when starting the flow, but leave just enough in that the source-end never lets any air in. Once the flow is started, just push the hose deeper into the source to make sure it hits the bottom or whatever level you want the source to finish draining.
I just hold the hose under a pipe..when water comes out the other end you simply close the ends or hold both ends up at the same level ( whichever way is fine, the goal is to not let the water in the hose escape and hence not let a lot of air get into the hose again)..put one end of the hose into the water to be siphoned and the other into a container to collect the water placed at a LOWER ELEVATION.. Now just watch gravity and Air-pressure do its magic!
What I love about this show is that everything is explained so simply and clearly. Explaining science and tech isn’t always easy. It takes skill, and they always nail it.
Yes - and they speak very clearly also, unlike most TV presenters these days “yeah - naah” … there’s nothing on TV anywhere near as good as this show. Oh - and BTW - I don’t have a pronoun!😮
Terrific video, I wished it was longer and talked about the limitation of this siphon's design, that it can't siphon all the water from the container, and got into to other designs.
people believe in God because its more plausible than the Universe popped into existence from nothing for no reason or from no cause. If you like you can look at it from a scientific and atheistic point of view and simple accept that evolution and our survival depend on having hope and finding a reason to live on in times of desperation and that there is a all loving God who loves us and protects us and guides us etc... Why deny your scientific evolution? If there is no God then truth does not matter and evolution does not care either way other than survival and whatever works best for survival works best true or not.. Why interfere with you need to survive if the truth does not matter? Denying God is anti-evolution, anti-scientific and anti-dna..
I have seen many videos on a water siphon and I did not understand it much this is the best video regarding water siphons. The person explains it unexpectedly very great. He shows that the water bounces when you release your finger while the straw is in the tank so, you need the straw as in it can go. That is very amazingly explained. Thank you soo much for this video. This was very good.
Dear, Rob and Dean, now.. this IS great science stuff for kids not old kids to re discover. Just loved these guys and so pleased they came from my home town of Adelaide. South Australia. So happy to have seen this and now want to see more. Many thanks to those who have made this possible. Great move !!!! Cheers, Colin now living in Cairns. Oh I’m so happy now !!
When siphoning from a closed vessel like a gas tank, you can just install the siphoning hose and an extra piece of hose or pipe in to the opening, after which you plug the rest of the opening air tight. You the blow in to the extra pipe creating pressure in to the closed vessel which in turn pushes the liquid up the siphon hose.
Rob and Dean, this show shaped my life. I'd watch religiously after school and you both imparted a curiosity in me about the world and science which has never left. Thank you!
I saw the curiosity show LIVE on stage.. I was an excited kid from the country. I think I might have wet myself! Rob and Dean were TV heroes, and the live experiments they did blew my tiny mind. I am now 47. Cheers Rob for getting online. What a precious resource. Drew
To avoid using your mouth for the first method, fill the tube with water or something first and plug the end with your finger, then insert the other end into the liquid to siphon, remove your finger from the hole and the liquid should begin to flow. Basically just fill the tube with liquid ahead of time, so the flow must continue when released.
I found this video by chance, and I found it very interesting! I work at a conventional surface water treatment plant, and this could be very useful for the procedure siphoning during Jar Tests. I will try to apply it, many thanks for this video!
I'm from The UK and have only just discovered this show here on RU-vid.The show is so much better than the stuff we had here back then.I'm just so glad I now have access to it.Subscribed but I know I'll be saddened when I've watched them all knowing there will be no more made!Thank you so much for introducing me to this!
@@CuriosityShow Thank you Roberto!, for all the entertainment & education. (i like many others watched this after school in the 80s. The Goodies, Monkey Magic, Curiosity Show, etc.) I wonder how many lives you have impacted, and the quality speaks for itself - top notch stuff. You should feel very proud of what you have done, even if it may not be tangible. CHEERS
With soft hose or tubing, just lower a fair amount of the tubing into the liquid, cover the other end of the tube, and pull the tube back out a bit and over the side, and open up the lower end of the tubing and it should flow. No sucking, no bending stuff. When you pull the tube out of the liquid with the other end closed, the liquid comes with it...
i feel like carrying around a small soft rubber tubbing around with me now. so when i go out drinking with friends i can use this method and then siphon their beer out into my empty glass. ill do quarter at a time so they wont notice
I made this today and I'm so Happy and Excited that it worked. My parents were excited to see that as well. Felt like I'm back into my childhood days. Thank you Curiosity Show ❤️ Love from India.
Amazing show - always looked forward to seeing rob and dean after school! Was super excited when I order their series of books ‘earth; wind; fire and water’ - mini experiments and projects all based around the elements. Good tv. Pity they don’t make shows like this anymore
They do, they're just not on cable television anymore, and are filmed in slightly better quality. There are countless educational videos not too different from this one all across youtube.
I ask for drinks without ice at the drive thru and then use this exact method to transfer it to a large glass that has ice from home in it so I get more of my drink. Thank you for making this and explaining it so well, now I get a lot more bang out of my buck when ordering drinks at the drive thru.
I used to help my Grandad brew beer and I remember the siphoning stage well; whether it be transferring the beer from the barrel to the demijohns or the demijohns to the bottles. Of course, we did it the conventional way. This, however, is an excellent cheat. I'm sure my Grandad would be as impressed by this as I am if he was still around. Remembered fondly.
I was a mad scientist kid living in Adelaide when the curiosity show started. They came to our school on occasion and did science demonstrations which I'm sure had a big influence on my life.
Fair enough, and if you like pub tricks where you can win a free beer, have a look at ru-vid.com and go to the tricks and puzzles playlist. Heaps of them - Rob
I used to love this show when I was a kid growing up in South Australia (where Winky Dink, Humfrey B.Bear and this came from). I think it may just be the thing that started a great, life long, love of science in my young and impressionable mind. So many hundreds (or perhaps thousands) of hours contemplating the wonders of nature and amazing scientific achievements, experimentations and discoveries. What a shame that love of science has absolutely no practical application in the real world and is at best, a costly distraction from the gainful pursuits that i should be explored instead. Who am i kidding ?....you guys are legends.
It's the best way to borrow your mate's martinis when he's talking to the bird next to him. Letter M, low hill, high hill, free drink. Then the barmaid cuts him off after 6 drinks as he has become rude and obnoxious, complaining he's had 6 drinks with no effect at all. Bonzer!
In the 1980's when this show was on This was the latest technology like smartphones and internet is now. Kids would then carry straws and hoses around in their pockets for a week until the next episode.
You ſcale the deſign up uſing wider tubing, which allows for a higher riſe. Alternatively, depending on the exact ſituation, you can fill a normal garden hoſe with gas (cap off the end and uſe a funnel and ladle laſhed to a broomſtick) or in a more general ſituätion, if you're juſt throwing the liquid out, water (aſſuming it's not much leſs denſe then what you're ſiphoning- it would not be an option for mercury). Then, keeping at leaſt one end capped (you may need to cap both depending on the diämeter of the tube), poſition the tube and uncap it.
Uhmm... no, the pocket knife is not "banned in Melbourne," the laws simply state that you cannot have a knife out in public without good reason. Nowhere near "banned."
I put a non-soil grow bed on top of my aquarium with a pump to fill it and a bell siphon to drain. I have never cleaned my tank because my grow bed is a huge filter and the plants take up all the fish poo for nutrients.
buy an eheim gravel vac. it's got a filter inbuilt, you just stick it in your gravel and turn it on and it sucks the crap out and holds it so u can empty. about 200 bux
I was never around to watch these programs. I was born in the noughties. But last year I was introduced to How?, which was a similar show over here in the UK. I guess from watching that I got recommended this.
Well, if it only works on fluid levels that are level with the 1st bend, doesn't really help much in real life situations (siphoning fuel, or other fluids) unless you want to siphon out the water from a full fish tank.
Run the hose under a tap, wait for it to be filled..close both ends and not let water out, put one end in the aquarium other into a bucket or whatever under a lower elevation... release!

Phenomenal explanation and I love the demonstration of making this at home out of straws; I need to remember to show this show to my kids when I have them
Oh my god. My mind is blown. I have a small 10L aquascape aquarium full of plants and drift wood, I was wondering how to make an automated system to stop water flow when I'm changing water, incase of a call or whatever reason it may be. I searched high and low and finally. This is genius! Thank you!!!!
Thanks. Curiosity Show was a national science program featuring Dr Rob Morrison and Dr Deane Hutton. It was made in Adelaide, South Australia and screened nationally in Australia as well as in Europe, Asia and Australasia (14 countries and dubbed in German for Europe) from 1972-1990. Deane and Rob intentionally used everyday items around the house (like old rusty cans) so that people could repeat the demonstrations with materials they had to hand. In 1984 Curiosity Show won the Prix Jeunesse International, the world's top award for TV programs for young people. Rob and Deane are steadily uploading segments at ru-vid.com Why not subscribe?
With the M-Shaped siphon, how is the water able to make it over the second hill? The second hill of a roller coaster has to be shorter than the first hill, so why is this different? Is it a wick effect?
No. It relies on 'dunking' it so fast that the water rushes over the first hill, and races down and up so quickly that momentum carries it over the second hill. Lowering it slowly won't work, and it also needs the second hill to be not much higher than the first, but as you can see, it does work if you get all the elements right - Rob
I see. I watched the video closer again, and you did drop it considerably faster the last 1/8" or so. But even so, without your finger on the other end, the pressure in the tube should be near equal. I'm guessing the small tube in relation to the viscosity of the water creates a slight enough delay giving it that momentum since you mentioned a small tube is key.
Rcbif - I'm going to disagree that it's the dunking that does it. Remember, he said the water level had to be at the top of the container - it's actually the fact that the low point that the water turns through is so far below the surface that there's added energy as it descends. this gives it more speed on the uphill - just enough to overcome the second Rise and start flowing through. It wouldn't matter how fast you dunked it, if the water was not up to the edge of the siphon container, it would not work.
Eric Kieber Energy can't come from nothing - the water has to overcome height, so it needs dunking (movement). So a classic case of kinetic energy transformed in potential energy.
- The energy isn't coming from nothing. The shape of the siphon pipe is taking advantage of the fact that water is heavy - it has to rush down that first descent in the "M" shape, and it goes well below the surface of the container. Because there is more pressure there than at the surface (due to gravity), it speeds up the water's travel. Then as it climbs the next uphill section, it has that additional speed to then overcome the slight height difference and keep pulling the rest of the column behind it, starting the 'siphon' effect. The 'trick' in this is when the water first goes over the lower crest - it can be slow until then, but once it gets past that it will flow very quickly and start siphoning. Hopefully that explains it better.
Y'all doing it all wrong 😩 just stick a little extra length of hose down into the desired fluid, cap the end of the hose with your thumb, pull the extra hose out, tip the end of the hose down lower than the fluid level and let your thumb off.... It's like playing with the straw in your drink at a restaurant just with a hose
