Made one this weekend. Took a little longer than expected to make the launcher and a couple rockets. But, wow. These flew higher than our normal rockets. The kids loved it. I was able to buy everything as described except I couldn't get the same size brass fittings. Instead the size between the brass fittings had to be larger to find a combination that kept the same size hose barb and PVC pipe size. Fun!
This is pretty cool. Lately my son and I have been making compressed air cannons. We've shot them through televisions, toilets, vases, etc. We have also fired a nerf dart over 75 yards. Have vids on my page showing them.
it's electrically actuated, so it's faster than a valve that you need to operate by hand. also if you make the wires long enough, you can launch from as far as you want.
This is a brilliant idea, incorporate a burst disk after the sprinkler valve ( simple as masking tape in a coupler near the end) this would give the rocket much more "power" if the chamber to barrel ratio is more than 3:1 because the air pressure is spread through the valve chamber and barrel.
Hey, we just did this today in my 3rd year highschool engineering class (think of it as a classic shop class, but with CNC machines and lots of expensive software). We built it ourselves, and the original design was apparently from Make. Anyway, the teacher challenged us build our rockets in 10 minutes out of 1 piece of cardboard. some tape, and no designs/planning of any kind. If it's any testament to how easy this project is, mine won the challenge with a distance of 189 ft at only 40 PSI.
I really have to say, to those who are confused. This is NOT a rocket. It is just a rocket SHAPED projectile fired from a "canon". A rocket is something that propels out something through one end, which then makes it go forward. Meaning: a rocket loses mass/weight as it travels.
You can also drill a hole in one PVC end cap and install that tire valve stem right into it. That will remove a lot of the reducers, fittings and the hose, a lot less clunky.
I haven't tried this compressed air rocket but I have built a few water rockets that require compressed air. The kids love them because they also get wet in the process and what kid doesn't love water.

Nice. Got mine flying to 150ft easily. Add a little water to the launch tube to give it some extra kick, although it shortens the life of the rockets. And make sure you put a fair bit of reinforcing on the nose or you'll blow the top off. Also, you can put an end cap on both ends of the long tube, drill a hole in one end big enough for a bike tube valve, then insert it and attach it with some waterweld epoxy putty. This stuff hardens like stone and holds the bike valve nicely. Press it firmly around the inside and outside of the valve. Then the valve is part of the launcher. I use rockets made out of thin plastic sheet - they fly way better and can be re-used hundreds of times.
@matrixman091 you can, but at about 80 -85 PSI (depending on the construction) the paper rocket will rupture. it is best to start out at 50PSI the first time you launch and then add 5-10 PSI each time you launch until it blows. I would not go over 90PSI as the you could have component failure in the tank or valves and the shrapnel would be dangerous.
I did something similar in jr high school except we built our launch pad out of wood, an electrical junction box, pressure rated clear tubing, slide pins, thin nylon rope with a plastic handle on the end (used as the launch cord). Our rockets were fashioned using empty 2 liter pop bottles and thin cardboard paper to fashion the tip and tail fins. Then the bottles were filled about 1/3 of the way with water, set into the launch pad, inflated to about 35-40 psi, then the nylon cord was pulled and the rockets flew a good 500 feet in the air. Good times lol.
if you were mess with the design a little bit you could make a hand-held version completely self sustained with a battery powered air compressor mounted on it. Make several rockets in like a sash and have an awesome hand held rocket launcher.
well it worked the first few times as you can see in my vids but it eventually died on me. i was really hoping to use an electric trigger. i wound up using an air gun and then scrapped the whole project and used a mechanical lever. was more reliable. but thanks KipKay for the vids. You i inspire me to no end. :)
Hey KipKay. I have been inspired by your videos but I think you could make your compressed air gadgets easier to build. If you drill a 13mm hole in your pvc end caps then pull through a standard (UK) car tyre valve it fits air tight and water tight easily up to 120psi. I'm not sure what US valves look like, but this might save you all those brass couplings and lengths of tubing. Thanks again for all your fantastic videos.
I made something similar when i was in school. The difference was that i used recyle materials, PET Bottles, recycled wood , coke cans... and my bicycle pumb...
Hey KipKay, I made one and accidentally launched it while bent over the rocket. It is now protruding totally through my skull after passing through the brain. Is it okay to just pull it out, or do I have to go to a doctor?
Hey Kip Kay i have a science fair coming up and i need to know why my sprinkler valve dumps the air so slowly? I click the button from a few feet away and it takes like 5 or more seconds for all the air to come out!
he's American that's why. It's just the measuring system he grew up with and learned the best. there are conversion tables for everyone to use. I use them all the time. Just google it. No offense or anything. Have a nice day. =)
@spencss1 The materials might cost $25, but if you read the description carefully it says "25-cent rocket." If you've made this and are having trouble making the rocket, take a sheet of paper and wrap it around a tube the same size as the launch tube. Tape that together and then wrap paper around it again, the second layer of paper will be the actual rocket. You can be creative with the fins, just hot glue them on, and the nose can be made by cutting a paper down the middle and folding it.
You can make the rocket with a plastic 2.5l coke bottle and create a cone tip for aerodinamics by cuting out the uper part of another 2.5l coke and taping it to the buttom of the rocket!
IMPORTANT: Be sure to use schedule 40 PVC not schedule 20 PVC. SCH20 is drainage line and is not pressure rated, at 75PSI it WILL BLOW UP in your face. SCH40 will have a pressure rating printed on it, also be sure to use pressure rated fittings. Honestly Kip you should have told the kids this.
you could make the rocket out of plastic or something that doesent get ruined by water and and add some water above the valve and put on the rocket, it should boost it alot
Great project! As you are using a sprinkler valve, could you do the same basic project and make a water rocket ? (i.e. Compressed water and air instead of just compressed air??)
How much pressure can that sprinkler valve take? If I'd change the PVC to SCH120 and put 300 PSI could the valve handle it plus larger pressure chamber? Rocket made out of PVC of course.
Made one this weekend. Took a little longer than expected to make the launcher and a couple rockets.

Remember when RUclips had video responses? Yeah, those were the good days...
Its fine now. I built it with the sprinkler valve and its so much fun!
4:55 If you look under the rocket you'll see that it breaks the sound barrier, Which is freakin amazing.
such wow such true.
ps do you maybe have a slowmo app?
That is just high pressure air coming out.
xD
Man it can't broke the sound barrier cause it's a lot more faster then that rocket (it's velocity is 340.29 m / s )....

i cant do your projects, but i enjoy watching you doing it.
@zivxx its 25 cents for the rocket. the PVC is cheap and the sprinkler valve is about $15.
This looks like fun! Unfortunately the link to the blog fails, tho. I'll check again tomorrow, maybe it will be up by then.

It's a rocket to my 6 year old. We're not trying to reach the moon.

This is something I'd be tempted to make.
When using pvc cement it helps to do quarter turns to better spread the cement and great videos

KipKay's back! He has such a great screen presence.
Yeah Kip, that's awesome that you built that rocket and all, but what's REALLY awesome is you ALSO made an air cannon...that's MYTHBUSTERS cool!
Great oppourtunities in that basic idea
Very nice video with vivid illustrations...Thanks for your time !
Love,
kris.
wow this is so cool this is the main reason i got in to engineering and science.
Looks like I have something to do Saturday morning now!!!
Nice shot, Kip!
Kipkay started it all for me years ago I remember this video being posted
I had a "Wham-O" back in the day!
Used the "free air" at the corner gas station
Kip, your videos ROCK. Thanks so much for the projects!!!

You went up to 75psi, but how do you determine what the max psi is for your pressure chamber before something cracks?

YAY!!! kipkay is back!
I have built one of these myself, and used a diesel can for a pressure chamber and a ball valve.
@jackol900 The rocket costs about .25 to make. Not the launcher
i can't wait to build it
if you were mess with the design a little bit you could make a hand-held version completely self sustained with a battery powered air compressor mounted on it. Make several rockets in like a sash and have an awesome hand held rocket launcher.
True dat. In the end I did end up building it with the sprinkler valve and your right, it is cooler.

fantastic work, no money new technologies good work
Cool!!! that's quite a distance!!
Nice job on the video. I made one with some modificaitons. Worked great for my pack.
that look pretty darn cool. I'm thinking you could use a plastic nose cone. However, the start up cost doesn't exactly look cheap.
well done man
Rockets are cool. Glass marbles and steel ball bearings work too...
This is really cool I'm going to have build one of these.
That's pretty cool! I can't wait to try that with my kids! :D

change the chamber and barrel dimentions and ad a bit more pressure and maybe a pressure indicator and youve got a pnumatic spud gun
Hey KipKay, I made one and accidentally launched it while bent over the rocket.
It is now protruding totally through my skull after passing through the brain. Is it okay to just pull it out, or do I have to go to a doctor?
Thank you kip kay, you teatched us how to make a FUCKIING KILLER LAUNCHER!
KIPKAY Rocks!! keep it up
We use one of these in my boy scout troop we have had lots of fun with it
I made a rocket but with water, flies cooler, and looks better in slow mo :) great vid
nice work
Cool project, except that this is not a rocket, but a compressed air propeller projectile
+rafalpilat145 i was about to say the same thing. And it could have been made a LOT simpler.

later i will show u my rocket i make it in my school science project haha.. but i love ur video so interesting..
I made something similar to this, but instead I use a bottle rocket filled just under half way with water! It works great!

U should put a few LEDs for launching this thin at night... And try 90 psi
Other than that awesome rocket !!
Looks like fun.
WAAOOO man ! ! amazing.

As you are using a sprinkler valve, could you do the same basic project and make a water rocket ? (i.e. Compressed water and air instead of just compressed air??)
WONDERFUL JOB
PLEASE KEEP IT UP
THANKS
i am about to make it soon
great video, please do more like this
Awesome!
I wonder how many tries it took to get that rocket in the goal...
it WORKS JUST GREAT
thx man
i'll make a lot of 'hem
awesome video XD
That was cool.
How much pressure can that sprinkler valve take? If I'd change the PVC to SCH120 and put 300 PSI could the valve handle it plus larger pressure chamber? Rocket made out of PVC of course.
Good Idea, can be done esier. Does anyone know which gas can be better compressed than air (oxigen+nitrogien)?
