Paper Rockets for Under Five Dollars (Physics)

[@fivenightsofrandomness9224]

This youtuber just leaked north korean nuclear missle plans

[@zaiben3234]

Hi

[@nandanvb357]

Yay now we can eat the rockets!

[@hofs9123]

Excellent project spent 15 dollars and 2 hours putting together building rockets.... Son did 95 % himself and entertained family and friends for hours when project was done :)

[@sameerkaravkar]

Same I spend 150 dollars 6 hours to complete my school project

[@sobaman6210]

Hi can I ask if all the 1/2 pvc pipes you used were a foot long?

[@TheGoat62607]

Wow this is amazing! :)

[@bencordero708]

I am thanking to you for the great idea you have shared. God bless you Sir.

[@chikumbindirudo3478]

Um mm what if you don't have the pipes what do you use please help me l am going to be having a project like that

[@therocketguy18]

No words to explain that's a great idea

[@Danz-Man]

a tip i have is to fold the top in while the pvc pipe is still there then smashing the top in that way the paper kind of makes its own seal, still add tape though

[@TravHouse]

So how do you get the bottle to blow back up to step on it again?

[@MarieRavelo-fq4tc]

Im a year late but u just press it on the bent sides

[@petermiller6629]

How many rolls of electrical tape are required for this project?

[@malachiconradi2119]

Thanks needed this for my tech class

[@awis7391]

How long are the pipes?

[@catsbored]

Thank you so much! We homeschool and this was an awesome(affordable)project for STEM.

[@BeardedScienceGuy]

+Angela Long If you google NASA paper rockets they have designed STEM lessons and experiments to try.

I make rocket but is not flying straight how do i do that

[@kelcieford7236]

Could you substitute construction paper for card stock? And can you substitute pool noodles (with minor adjustments) for the PVC pipe?

[@BeardedScienceGuy]

Regular paper would probably be better as I think it may hold more pressure. If you don't have any other paper construction paper would work just won't hold quite the same pressure witch won't likley matter unless you use an air compressor to launch it much further.

[@emilyfox8604]

Can you reuse the 2 liter bottle, or do you recommend changing it out each time?

[@BeardedScienceGuy]

You can totally reuse the bottle but the 100th rocket won't likley go quite as far as the first one. If you are doing a lot I would also have 1or 2 back-up bottles incase it breaks when stomping on it really hard.

[@jp8ntsk8p]

I like that you keep construction simple.

[@bencordero708]

Is there any way to increase the isopropyl of an alcohol from 75 to 95 percent?

[@BeardedScienceGuy]

Yes, you will need salt. You can salt out the water and get above 90% isopropyl but with salt dissolved. Then if you need to remove the salt you can use distillation to get relatively pure isopropyl mixed with very small amounts of water.

[@ghulamfareed5665]

That was nice man

[@God.did.1.2.3]

You are the best person ever

[@Mahasnito]

Hello I know it's been a while since you uploaded the video but I have a question? How far does the rocket go I really want something to impress my friends with.

[@BeardedScienceGuy]

Stomping on a 2-liter bottle it will go about 20 meters give or take. Using an air compressor at 80 psi and an electronic sprinkler valve, a good design will go closer to 100 meters.

[@jaydonmahar5123]

wow its so amazing

[@kishorekannankannan2504]

very nice brother

[@ehudmusare6695]

am definitely gonna pass class.thx bruv.

[@tanyayarmola7566]

i like how you showed the rocket

[@27nadira]

As a kid I want to be a scientist partly because of this.

[@clareeve]

great video

[@yubrajhamal1831]

Wow amazing nice 😃😃

[@mayher2069]

How many stomps until you need to replace the bottle?

[@CyPhi68]

Perfect. I am looking for a simple ballistic project for Upward Bound this summer. This is it. Cheap, show students the video and let them build it. We will measure the distance as a function of the angle. We can record who launched it to help keep the force similar for each launch. I think we may put vanes on the fins to (perhaps) spin stabilize the rocket. (Upward Bound is part of the TRIO program in US Dept of Educ. Celebrated 50 years in 2015. Check it out. I am sort of retired and have been doing Upward Bound for 8 years. Plus tutoring for a community college. Both keep the neurons firing. )

[@BeardedScienceGuy]

If the fins are applied to the body at a slight angle it will also stabilize with slight spin.

Next time, how to make a nuclear reactor with uranium and a LOT of electrical tape :D

[@generalgreen77]

😂🤣

[@fahdbinrasheed7244]

What is the benifit of elbows ? Why didn't make it straight ? Because the elbows effect on the air flow which is the source of flying

[@BeardedScienceGuy]

Fahd Bin Rasheed The elbow allows for an easily adjustable launching angle but it does decrease the power at witch the rocket is launched.

[@erwinhewitt7438]

this title should be how to subdue the attention of 100 after school program 8 year olds in one shot

[@aa-ik2wh]

Loved the video.

[@MrTrostrekich]

This is great! I needed a Science Experiment for my students at our science fair at end of April! I will use this over another one I found. I am going to compare different bottle sizes to see which has the greater thrust give the same amount of pressure on the bottle. what do you think? thanks again1

[@BeardedScienceGuy]

+Roy Trost-Rekich The only trouble would be controlling how quickly the pressure is applied if someone steps on the bottle. Using a falling object would be the most consistent that I can think of off hand. In the classroom we use a pressurised PVC pipe with an electric sprinkler valve to launch rockets and it works great. Pressurize to 30PSI and then open the valve with three 9v batteries and the rockets fly impressively far. It's also very consistent.

[@christianeniolaolowooloja1529]

Nice bro

[@fungamesfriend7904]

I tried this multiple times but endeavor works also they cost way more than $5

[@mateoschannelhush6963]

Does the rocket have to fit in the pvc pipe loosely or tight?

[@jameshambley966]

It should fit as tight as you can where it still slides up and down the PVC easily.

[@Kamika_C_1980]

so how many rolls of electrical tape do you need?

[@nickdesert7304]

Kamika C 1 million rolls

[@DaSunfish]

lots

[@PremSingh-mm4he]

Yes it work well

[@karolissv9302]

i wish i had all that stuf

[@waynemccuen8213]

You can use 2 bottles connected with 2 90 degree elbows and a "T" fitting between them then out to the 2 threaded elbows launch tube for more "thrust"! That way, you and a friend can jump on them together and have it fly even further. Then you can get 2 "chubby" friends to jump on the bottles and then it'll fly REAAAALLLLLLLLY far...........I think that's how Iran launched their scud missile's.

UPDT

[@burk3385]

Umm, that rocket went like 50 feet. What happened to 300 feet?

[@BeardedScienceGuy]

I wanted a video shot where the rocket landed in front of the camera looking back at me and if you stomp hard enough to get 300 feet the rocket is not accurate enough to land in front of the camera.

[@userr2706]

angle?

[@sonudaiya8411]

I will come first in science week thx bro

I do in my school exibution

[@anthonyb5279]

this is how not to do it. what does that rocket weigh like 2 pounds. use thin paper and cellophane tape.

[@BeardedScienceGuy]

Air resistance will have a greater affect on a lower mass rocket. Someone better at calculus and physics than myself could find the best design but the lowest mass rocket also doesn't go very far unless it is in a vacuum.

[@anthonyb5279]

@@BeardedScienceGuy "Someone better at calculus and physics than myself" Yep thats me. Im an actual Rocket Scientist and I did teach kids at Space Camp to make stomp rockets. You are way past the optimal mass to surface area ratio. 4 paperclips in the nose is optimal and doesn't make much difference, just increases the stability by lowering trim drag. Any heavier than that you get diminishing returns.

[@BeardedScienceGuy]

Thanks, thinking back this design was for our 80 psi electric sprinkler valve launcher and I just reused it for the stomp video. Covered the pvc in fiberglass after NASA pulled their plans after a launcher rupture. What are your thoughts on this design for the 80-100 psi launcher? We usually throw in a very slight tail fin angle for spin stabilization.

[@anthonyb5279]

@@BeardedScienceGuy I think you should stop pretending like you know what you are talking about.

[@BeardedScienceGuy]

Anthony just curious where you went to school and where you work? Trust me, at higher launch pressures the light ones have stability issues. I'm not sure why as my background is primarily in Biology, Chemistry, and Teaching. However of the professional scientists I know, I can't think of one who would respond like that, thus my question about your credentials. Thanks

Hi

why not do a rocket using cocka cola cans that realy flies get it.😀😁🤣

i did this experiment today at my school and my rocket went nearly 70 feet in the air! I have a video of it aswell if anyone wants to see.

[@divyascientific2805]

we can use cardbord

[@BeardedScienceGuy]

To work well the tube needs to fit tightly around the pvc pipe and cardboard might be too loose but experiment with cardboard and paper and see what you find out.
