- A siphon is an effective way of moving liquid from one container to another, but sucking on that tube can be unpleasant and even dangerous. Rob shows how to make a self-starting siphon that moves the liquid all by itself.

I was born in the early 80s, but somehow managed to completely miss out on this show, until I discovered it on CZcams. I would've loved this as a kid, and will happily show these clips to my son when he's old enough.
Seems like a British show
Australian. made in Adelaide, South Australia, 1972-1990 and exported around the world - Rob
@@CuriosityShow It was definitely exported to germany. I watched it as a kid in the 80s and I loved it. So happy to have found the channel. :D
They still have this show out in California but they renamed it to the Bicuriosity Show
@@Cfass1 bruh nice joke 😂
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.
Wow... just... wow...
What are you talking about, he wanted to top off his Brain
that happens about twice a week in every country that has trailer parks and fuel theft.
A CZcams 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
Thanks for that story ROFL. My wife and I had a really good laugh reading that.
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.
Many thanks - lots more at czcams.com/users/curiosityshow with new stuff each week for subscribers - Rob
for real dude. without a doubt correct man
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!
Nice username. I guess it was inevitable
With the steady increase of gas prices this information is valuable. Close to 10 dollars a gallon by next year.

Uhhh... if you watch it with auto generated subtitles it says something... welll uhh... special in the beginning
derik yolk LOL
Thank you so much.
Kill me. I am dead already.
also look at the last 6 seconds
derik yolk hahahhaha lmao
That's the beauty of science. Scientific phenomena can be as interesting today as they were hundreds of years ago,
Rob
CuriosityShow just like when this video was made?
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.
CuriosityShow absolutely!
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..
+200jago Please don't start this shit.
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.
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 !!
Very kind of you - Rob
Rob and Dean are the reason why i became a technician and started my company. Thanks fellas 🙌 (and macgyver too)
Our pleasure - you probably had it in you all along - Rob
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.
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.
My great pleasure - please spread the word - Rob
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
Very kind of you - Rob
More than 35 years ago I used to hurry home from school to watch this show on the TV.
Rob and Dean, I hope you have both aged well. :) I have.
Thanks very much; both still going and involved in science education - Rob
Me too! 4 or 4:30pm on Channel 9 if memory serves.
lolll fantastic comment
You were sat bored in school and ran home to watch this? hmmm
@@shaunohagan1491 Yes, the alternative was cartoons that were purely commercials for toys - like He-man or GI joe. The choice was simple.
This episode is gonna come particularly in handy these days. 😂
Now they just need another video on how to get open all the different type of gas cover opening locks on vehicles these days.
LOL
its sad how broke youtube algorithm knows I am XD
@@mbuckley3828 the lockpicking lawyer covers that lol
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.
Great idea! Thanks
Man I am going to empty so many tanks :)
that's assuming that the hose is not too big in diameter, otherwise you'd have to plug both ends of the hose, and that won't work in many scenarios
Inb4 water in tank
Gonna use this water prefilled idea on my gas tank cuz I too like to live dangerously
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!
A great pleasure. I think it is an interesting bit of science rather than being a practical device but if it works and helps, I'd bve delighted - Rob
The Phenomenon of Capillarity, this applied in oul industry and there producing tubing are sized for maximum up lift from down under.
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!
Great, thanks very much for thiose kind words, lots more at czcams.com/users/curiosityshow - please spread the word- Rob
I loved this show. And... I am noz sure if there is something comparable today. Interesting, sympathic and without any special extreme show off.
It’s amazing to see that you’re still active Rob!
My thanks - still kicking on - Rob
Great, now with the gas situation I can siphon my neighbors gas tank easily, thanks curiosity show!
Sure, if you can find a gas tank which is filled right up to the rim! 😂
Very useful info. I have used the first method to start a drain pipe for an aquarium for 40 years now.
Great pleasure. lots more at czcams.com/users/curiosityshow - Rob
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...
@My Thoughts his method uses the water's momentum, while this one uses the water pulled by a partial vacuum, no need to rely on momentum
I use this method for seawater aquaria regularly. It is the most straightforward method of siphoning with a flexible hose.
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
@@eddielopez3449 how did you get on?
yes. _100%_ accurate
I'm from The UK and have only just discovered this show here on CZcams.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!
Very kind, thanks - Rob
@@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
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.
One of the things I enjoy the most is listening to an english speaker using the metric system. What a pleasure!
I adored this show as a kid, I really did. Some of the lessons from it stick with me still 😁
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.
Thanks for that, and for watching. lots more at czcams.com/users/curiosityshow so spread the word among fellow science lovers - Rob
I'm going to have fun with this at the pub.

OMG! I totally forgot that I used to cut and connect straws up like that when I was a kid! I must have picked it up from this show!
Now that’s the best segment of this show I have seen.
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.
Great job - thanks for the comment - Rob
That siphon looks like the 08 housing market.

that siphon looks like my wiener.
Oddly specific but clever and funny
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.
I've had the 'couriosity' song stuck in my head for eight years since first seeing this video. Thanks.
My recommended is fucked up....
THE OFFICIAL DROP BUTTON FINDER It isn't, it's trying to tell you something, turn on subtitles right at the start.
iCannoNz im assumeing it used to say kill me.....it says q me now
davezf89 no way it changed rip
I don't know how i got to this video but I'm now intrigued.
i've been transported back to 9 years of age!...I loved this show.
This channel is awesome, I can't believe I just found it this week
that end was abrupt
CURIOSITY!!!
zirioz kcufin great
For real he really rammed that last one home
It was over as soon as he stuck it in
( ͡° ͜ʖ ͡°)
Boo
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 love this, the aussie accent, the presentation, it’s all so amazing!
This man gave me a great idea with what to do when I don’t have a coffee strainer
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.
I used to get sick from the petrol before I saw this video. Thanks CS!
This show is timeless! My 5 year old would love this! Just as I loved this show when I was about 8 in the early 90s, when it was broadcast in Israel.
Many thanks - we didn't know that it got to Israel - Rob
Suddenly in everyone's recommendations, huh? Reply if you're reading this in August/September 2018.

I love how he explains the simulation physics, like he's some kind of dev
You mean a physicist?
I watched this show as a kid in Australia. Was awesome
I loved watching this show as a kid... and I still do now.
CZcams recommended knows exactly what I'm into.
This was recommended, this is CZcams, this is my life...
I hate you, honestly
EUREKA !! no more need to look for an assho e !! HE IS HEREEE !! honestly !!
Haha and were also reading and reveling in comments.
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!!!!
No problem. I designed one with PVC using a slightly different layout (tube in tube) and it works as a self-emptying device on a tank - Rob
This is the channel that Dads come to to learn all the knowledge that we store, to then never really use, only to teach when the question is asked.
I'm gonna do something like this to clean my aquarium! Much better than the manual pump that breaks every 3 months!
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
Audio: "curiosity.."
Subtitle: "kill me"
I think we need to call the police.
What a marvelous show this was. No wonder i loved it as a child
My car has been out of gas for awhile, thanks for helping me to figure out how to get more!
This will come in so handy then next time I need to steal gas from a fish tank.
lol
Observation: With a fairly standard bendy straw auto-starting benefits from the syphon being dry. Any water trapped (especially around the rough bends) tends to put a spanner in the works.
I think a lightly wider tube/straw with smoother joins would help
I don't know how I ended up on this show. 3 videos later I'm bloody glad I did!
Watched the first video ever on this channel ... subscribed instantly
Very cool.
uhm...so what if the gas tank isn't filled to the brim....
which is the most likely scenario. Useless tip.
Then you use the first method!
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.

Forgot about it and finally came across it again
CZcams never recommends you, I wish they would
So do we!
I remember watching this show, it was great for kids and teens, was a keen to always watch each episode
This guy reminds me of Tim Rowett so much.
3:15 Hey that's pretty good
This is important information for everyone trying to keep their mouth clean while stopping for a bump of gas.
If you have ever watched farmlands irrigate field crops, the don't use a double bent tube. They use a single bent tube and from years of practice, they run the bent tube into the shallow canal and get the tube running and the next and so one the full length of the field.
The Quarantine recommendations are on point. I really need this right now.
vsauce michael here
Late night youtube is the best youtube. I always only get these videos on my reccommended late at night or early in the morning.
I missed out on this show probably coz I was busy adjusting the antenna... However I'm glad I get to see it now
does this count as vaporwave?

Who's here because of Vsauce.

That was great, first time I've seen this channel, and I like it.

Banned in California (straws).
Look at his pocket knife... banned in Melbourne.
Beard banned everywhere
I was bout to say!
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."
Is self defense against fruit a good reason?
He a gangsta!
Here before the video blows up even more due to Vsauce.
Irrigators do some interesting things with syphons . They can use dozens of 2or3 inch poly pipes to syphon over a channel bank to water a crop, starting them in seconds using the palm of their hand as a valve. We also use large diameter syphon pipes (9inch and bigger), these are started with an air pump ; two requirements, #1 the water level has to be above the paddock level ,#2 both ends need to be under water to get a start.
I grew up watching this and was very pleased to find it again. I wish I understood why really great television like this gets axed, same for The Inventors just to name one more. But yay!
Ding Dong, Michael here!
that whistle at 3:35
We used to make these out of bucket & tubing for hanging under steam leaks. The hose was routed thru a hole a few inches down the side of the bucket. That way we could estimate leak size by the number of times the bucket self emptied during a watch.
So glad I was an 80s kid for this
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.
Anyone got this recommended after watching Michael on DING?

AHA! Just the idea I needed for my wet sump aquarium tank ... so in theory if the power were to go out, water slight lowers in the tank. Power comes back on and water begins to rise and the auto siphon kicks in and starts feeding water back into the sump .... GENIUS!!! I've gotta get this working!
My favourite show as a kid in the 80s, kicked off my ongoing love for science.

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 czcams.com/users/curiosityshow Why not subscribe?
I grew up with Mr. Wizard, but shows like this with him would’ve been freaking awesome.
