String Shooter Pipes....air driven

[@ZipStringOfficial]

Bruce, you were our inspiration 8 years ago and still are today. What a great video and explanation! The triple string is epic!

[@1a1u0g9t4s2u]

I have figured out that with my grandkids, that if I simply give them a 'Toy' (one of the projects Mr. Yeany posts) they will play with it for hours. Only after they have had their fun they are more receptive to learning how it works. Hope you continue to post these for many more years. Thanks for sharing.

[@newmonengineering]

This is the science teacher I wish I had. Where were all these superstar teachers when I was in school?? Keep up the great work.

[@reypolice5231]

Collecting a paycheck weather you leaned anything or not. Your a lifetime learner, some are not.

[@Bear-nu8xm]

It's so nice to live in a world where people are interested in unique things to share with everyone!

[@twiho]

Anybody else wants to give this man a hug and squeeze him like a puppy... So inspirational.

[@ChristianBehnke]

Bruce is the best teacher I never had. Kids must be overjoyed to be your students. ❤

[@abpccpba]

You have done it again; Saw That Big Smile. It is great to see the child emerge from Bruce.

[@Nighthawkinlight]

This is great! A ton of fun for a kids group. I may try it this summer

[@YeanyScience]

may try it?? I'm expecting to see it bigger and better on your channel.

[@getaclassphys]

This is very good idea for physics theater, of course.

[@benjameniveson7079]

Good to see you still have a creative mind, remember "big ideas hide inside of little ones" laying there in wait for the correct observer to see it.

[@reypolice5231]

Bruce you got the juice. Young at heart and making learning fun fun fun.

[@marcus_weber]

Dear Bruce, it's amazing, how you come up with new ideas all the time! Congrats!!!

[@getaclassphys]

Потрясающе! It is a tremendous thihg! You are the best physics teacher in the world. And your dog likes your amazing experiments, I see.

[@YeanyScience]

She seemed to like watching the string as it flies, and since she's still a puppy would play with it when it was on the floor, I had to replace string several times due to being ripped apart or too heavy due to dog slobber

[@kristinpucciniyoung649]

Oh the kids are going to love this. Awesome! Thanks a lot for the fun episode 🙂

[@stowphysics]

Thanks Bruce. I always love seeing how excited you get. Don't grow up.

[@fizyka.nietylkodlaorlow]

These demonstrations are just wonderful. I really enjoy the simplicity of your ideas. At one moment you said that this is a demonstration of Bernoulli's principle in action. I am not sure. When the pipe gets narrower then yes, we can call Bernoulli. But the string is sucked into the pipe after the constriction, where the pipe is broad. I am not an expert in fluid dynamics but perhaps we have a low-pressure vortex after the constriction. Edit: Probably this is what happens. A fast jet of air above the constriction entrains air molecules present just after the constriction and below the jet line. It causes lower pressure. This is related to the Coanda effect.

[@fourierautomation51]

Just want to congratulate you on no only this video, but all your great videos. It's obvious that your students love and appreciate you. That must be very fulfilling. Best wishes.

[@YeanyScience]

Thank you! 😃

[@Hdtjdjbszh]

I absolutely love the potential for mischief these hace

[@ostanin_vadym]

Thank you for practical science.

[@OofHearted]

I have recently got a ZipString from their startup campaign but I had no idea there was already this manual, air-driven version that's so similar and easy to recreate in different ways! I honestly thought it was going to be a ZipString video because of the thumbnail, before I read the title.

Issac Arthurs orbital rings and active support videos are great follow ups to this!

[@JoaoZagoSJC]

I will definitely build one of these... just amazing, Bruce.... just amazing.

[@LakeNipissing]

You are just simply awesome, Professor Yeany!!

[@jenkneejpg]

Wonderful video! I think these could be used for practical effects for creative projects, very inspiring, and so cool!

[@killersugar6816]

Best science teacher ever.

[@MaxPowersHedgehog]

Very good Bruce, my favorite episode now! I love the 3 strings in one. Oh! The view as you "shoot" the camera with the string! Brilliant how you created the effect even w/TP

[@B9Robot]

THANKS for the upload and your work. My mind is going crazy on how to use this. Thanks for sharing your wisdom. #NewSubscriber

[@sciencetoymaker]

Excellent!

[@supaorigamisensei]

Definitely sending this to my partner for her girl guides classes thanks for the inspiration I’ll ensure she mentions you in her class

[@Tann114]

Thanks for this Bruce, you're an inspiration

[@JAdams-jx5ek]

The toilet paper was perfect. Very nice demo.

[@thomashendricks33]

Thanks for the video, Bruce! Great as always.

[@watt4126]

Woah, if you were my Science teacher I'd have learnt so much more! This is so engaging

[@louisepool3685]

Bruce, very creative and you did tell me your dog follows you everywhere 😂

[@YeanyScience]

She's like my shadow, it took me 3 times as long to make this video as I'd have to take a lot of breaks with her, also she liked to chew on the strings, they don't fly well with dog slobber

[@DanielGBenesScienceShows]

Absolutely brilliant demonstrations of this effect taken to the max! I’ll be sure to credit you when I use a few of these in my future live science shows!

[@ahmetizmir1081]

A breathtaking invention

[@Gambiarte]

Now I NEED a string shooter!

HI Steve, easy solution, go back to playing your video games.

[@slimnim1753]

I a really enjoy when you make super sized stuff 👍

[@squarebob62]

what a wonderful revelation!!! I keep thinking about one or two of these near the front porch on Halloween, with remote control and piped in big air supply ( I have a bounce house blower and some big PVC pipe. Thanks for all the Fun ideas.. Salute !!!

[@foobar879]

Doesn't it generate static electricity when you have all that yarn in friction with a plastic tube ? Makes me think about van der graaf generators. A string shooter that also shoots alectric arc would be awesome 😇

[@YeanyScience]

Yes, after running the strings for a short time, the would stick to the walls or to the hanging sheet, I'd have to keep it far enough away or it affected the flight

[@scottk3292]

Really interesting at 5:18 - I see one node at the house pillar, where the curvature changes. I'm pondering why the lower half of the shape isn't a catenary, but momentum factors heavily into this. Now I'm going to have to build these into the ducts in my home, so when heater turns on it's an art exhibit.

[@javiergenovese8064]

Muy buen trabajo . Muchas gracias por compartirlo. Saludos desde la República Argentina

[@Rararawr]

I wonder how far an air powered version of this can go. Using a motorcycle to move the rope, another youtuber, Joel Creates, managed to get a loop of 196 feet working

[@getaclassphys]

There was a project of a flexible antenn tower which acts this way.

[@woowooNeedsFaith]

Thank you. This was truly amazing...

[@YeanyScience]

Glad you enjoyed it!

[@extnctionist6158]

the real grandpa moment when he said "I call this one cotton candy" lmao

[@hisheighnessthesupremebeing]

I was wondering if there were any use case for this... Other than removing cobwebs... The only thing I could think of was building a race drone obstacles course (Red bull air race style) with a bunch of the TP version

[@YeanyScience]

Love the removing cobweb idea, high up they are always hard to reach, this would make it fun. The drone obstacle could be as easy or hard as you want to make it by adjusting the air output

[@Zekian]

Space elevator? Hahaha

[@huananina]

I wanted to go to bed, but this stuff is seriously interesting! :o

[@MrFmiller]

Cotton candy was fantastic. The toilet paper recycler is innovative. Better than reusing.

[@thedevilinthecircuit1414]

Fascinating stuff! I think it's not so much 'lift' that causes the string to fly; I think it's a combination of the Coanda effect and entrainment.

[@YeanyScience]

there are several papers and videos that have been produced on the subject if you want to know more about it

[@doraedapter]

Very interesting. Thank you for movies

[@rosco4659]

I wonder how many metres per second the orange string version you made was doing? You could hear the joint clicking if we new the length of the string we could easily figure it out.

[@simonpajger1331]

Hi, I have a question about the forces acting on a string. You draw a lift pushing string upwards, but I really dont see where this force could come from. Isnt it just drag, pushing string forwards, that is causing this?

[@YeanyScience]

If you watched my original string shooter from 2014, my theory is that it was inertia carrying it forward, I was soon proven wrong, the lifting force is coming from the atmosphere's pressure being greater than the pressure of the moving air stream. You may want to watch science lab's demonstration with shooting strings listed in my comments

[@getaclassphys]

@@YeanyScience I think your theory isnt fully correct. Of course, you are right when you write about inertia for the initial flight of the string. But what force acts on the whole loop? There are gravity which resultant is applied to the center of mass of the loop, and the aerodynamic force which acts along the string (and to what point acts the resultant of this force?). And those two forces must be equal in magnitude and must create equal torques, so they act along one vertical line. This condition defines the shape of the loop.

[@Dante8629]

Im going to try with a backpack blower😁

[@outdoorlegion9939]

[@user-rw1mo6vg7z]

its weird when your in school as a kid you never want to learn stuff. then as you get older and arent in school, it becomes almost something you seek out. odd how life is. if this guy was my next door neighbor id pick his brain for all the information hes got. and make a cool friend at that.

Awesome video. Would be cool to add some soapy water and see if ti could make huge bubbles too!

[@nvmnvm8821]

There's some exciting science involved with microphones, you might want to check it out.

[@YeanyScience]

Yup, that and I spent a year remodeling the second floor to my garage to use as a studio, all bare walls, sounds like an echo chamber

[@nvmnvm8821]

@@YeanyScience I'm sorry if I came off as sarcastic and rude. I really appreciate your content. You can make cheap and stylish absorbers out of fiberglass insulation and canvas if you want less echo. Another solution is to use a dictaphone with a wired microphone to record audio. A bit more effort goes into the editing in that case though. Keep the videos coming regardless!

That fuzzy string could be a big static electricity generator

[@YeanyScience]

You're right, after running it for a while, the string would stick to the wall or the hanging sheet

Not sure which was better looking. The fairy floss shooter or that lab.

2:17 I love your smirk, I want the same on my face, that’s why I have to make the thing with a straw and a thread now. 😏

[@coasterairtime]

I wonder, if you had a computer controlled precise blower and some kind of automatic pertubation mechanism that flicks the string, could you make some stable shapes?

[@lightdark00]

Nursing homes need a toilet paper shooter to make their jobs more fun to clean bottoms.

[@richardskull5279]

Seems there is also another effect going on. Like if you toss 1 end of a long chain in a container on top of a building. The chain pulls up in an arc before falling to the ground.

[@Maninawig]

Why do I feel like version 3 will be focused on a hand drill tredle?

[@jbjuren]

Instead of the blowing thing, wind could be used i suppose, and the spinning thing (with the toilet paper) could be a generator?

[@arkatub]

Can u add electricity or fire to the string? Both would be awesome.

[@jasonhaymanonthedrawingboard]

You don’t reckon that you could turn one into an electrical generator? Using something like a silicon impregnated resin? With a blend of nano particles? Essentially custom making a magnet tape that run through coils? With the search for eco friendly solutions? Would it be possible to generate electricity this way?

[@YeanyScience]

I think that may be beyond my capabilities

[@jasonhaymanonthedrawingboard]

@@YeanyScience thought it might be worth the ask? Or just throw the idea out there like a boomerang and see what would return? I’ve spent the last few days thinking out how it could be done with a few guy on Airborne Wind Energy Systems (Awes) forum. Considering the potential applications? Considering scaling potential? I’d argue you weren’t all that far off, coming up with something? Paint rollers was a genius move. So not too far from attaching a motor/ generator. It just a question of how well it work in the wind? Laddermill has been mentioned in our discussion on the forum as similar variant. I’ve proposed three basic variants ground based, hybrid and fully airborne. With the airborne version using the loop as a streamer? Definitely near your pay grade? Would be fun to see some numbers?

[@railspony]

With better paper and a leaf blower, I could install it in my bathroom and say goodbye to the bidet!
