My kids and I attended a local Maker Faire recently, and while there we got to shoot some paper rockets with a pneumatic launcher. It was super fun, so we decided to make one of our very own!
This project was basically the same as the pudding gun, so I went to the home center and bought some PVC pipe and joints to make the launcher's structure. I wanted the base to stand up while being small and compact, so I cut smaller sections and snaked them together with some 90 degree unions to form the air chamber. I salvaged the electric solenoid valve from the pudding gun and connected it to the chamber using a threaded adapter and some teflon tape. A smaller piece of PVC pipe extended out the other side of the valve to make the barrel that would hold the paper rockets. Rather than being CO2 powered, I used a shrader valve, like you'd find on most tires, and added air with a bike pump.
After some initial testing, we found that the volume of air in the chamber wasn't that great and our rockets weren't flying as high as we'd expected. So, we went bigger...much bigger. Josh made a pneumatic air cannon in college, so I sent him to the store to get some upgraded components. He came back with a 24 volt sprinkler valve that would attach to a 4 inch PVC chamber, nearly quadrupling the volume of air capacity. We used the barrel from the smaller version that held the rockets and glued in some adapters to match the new, larger pieces.
Because the new valve ran on 24 volts and because we wanted this launch site to be portable, I rigged up 3, 9 volt batteries connected together to make 27 volts. This was enough power to operate the air valve so I spliced in a huge "blast off" button that would send the rockets to the heavens.
After some pretty impressive test fires, I had the kids make up a batch of rockets and it was launch time! The kids and I had a blast pumping up and firing the rockets. It was a great way to introduce kids to rocketry and physics-based concepts and I'm so happy I made a version of my own. If you liked this STEAM-based project, check out more of my work!

The old rocket stuck in a tree thing : ) looks like fun Bob, GOOD STUFF!
Jon Peters Art & Home that tree thing is a tree lol
Jon Peters Art & Home lol
lol
Looks great and that you children are having fun that is the most important part of the build.
Will be making this for my sons this weekend, Thanks Bob!!!!!!
Really lovely , I am very happy to see your kids are happy with that 😍
Skillshare is awesome :) And so is this project. Keep it up!
Love it when you include your kids in the video. And great project too.
You are one of the few channels that I don't mind hearing the ads in the video, you do a great job of integrating it into the video while still showing work being done. Most other channels bring everything to a screeching halt to do the add. Good job!
Love it how the pressure tank says..,,’not for pressure’ . Great project Bob. Will gave to make it with my kids one day.
Your son is like me in front of camera "what do I do Now? I just look at the camera I guess " great project bob. I did the potato shooter version years ago with my son. It was fun
Did you keep the little one? You could have very one-sided rocket launcher launch-offs :D
EvanAndKatelyn why would he get rid of his kid?
Areeb Rasaq bahahahaha!
Hello
Loved the bloopers
I made this sane thing but used two pressure chambers, and this video told me a way better electronic system and was way more explanatory than all other videos. Love it!!!!
Heck yeah man. This is awesome. Thanks for all the great ideas! It’s awesome to see so many cool thing in one place. My family owns a fj60, so we’ll hopefully be making a tool box like you did for your 80. Keep up the good work man!
Nice touch with the car on the front of the rocket :D
Great project/video! It's great to see the kids involved. A couple of tips for anyone making this: 1. Wrap Teflon tape in the same direction as you tighten the female fitting so it doesn't bunch up. 2. Gender your quick-connect electrical fittings so you can only plug it in the right way.
love it! totally going to add a "space division" to my wood working. keep the great ideas coming!
Definition of a great dad!
Awesome Bob! A simple and very amusing project
Thanks bob for going in to great detail, I have been trying to make something similar for ages,
Thanks!!
Loved the subtle SpaceX reference at 6:29
the best part is: keep your kids be inspire and happy in the same time.
good works!
one of the best youtube channel for a looooong times
My son and I made one of these last year. We kept adding pressure until the rockets would fail by exploding out the side. So we wrapped them with tape to reinforce them and went until failure again. It was a great engineering lesson and fun too!
The coolest dad ever !!!
The intro and your reaction to the rocket going off alone was pure gold
Nice project ! Good mix of wood, electronics, metal and air pressure... And nice Music also !
Looks like a lot of fun for the kids!
Bob that was really cool. I'm going to make one for my grandkids. I think they will have a blast this summer.
Thanks for sharing
What great memories your creating with the kids!
2 months for 99 cents? I'm in. Thanks Bob.
Definitely gonna be making this for my kids!!!
Nice project. It is lovely to see that you make also projects that kids can use to play with it. Hopefully there will be other simular projects. Keep up to good work.
The little red car on the nosecone was a great touch!
Great job! Now comes the parachute assembly in a double stage.
Hey! I've made one of these! Fun build and the kids love it.
Looks like lots of fun!
Well done. We made one like that when my son was about the same age as your oldest. We still get it out a few times a year and now he’s 17. That thing brings dads and kids out of their houses faster than an ice cream truck. Instant block party. They say that PVC is unsafe at any pressure, so we wrapped ours with about five layers of duct tape. If it ever cracks hopefully the adhesive holds down the potential for shrapnel. A kid with a hand pump rarely has the patience to get the pressure very high. Keep up the good work.
such a great project! I love how you make things that awesome to make and soo much fun the the kids!
I had a commercial version of one of these when I was a young boy and you had to put some water in the small 6-8" long plastic rockets and pump the small unit up with a tire pump. This looks similar in function but on steroids. Great project and it gets kids away from video games!
Sweet, Bob! I might make this!
award for 'cool dad of the year' goes to...
love this! keep up the great work!
You really are an awesome Dad! Keep up!
Awesome work Bob! 👍👊
Bob's thinking..."I need to make this bigger...much bigger..." That. Was. Cool! Love the vids with your kids!
Sweet one, man! Looks fun!
Very cool! I bet the Air Burst Rockets would work great with this.
Love the little roadster you put there! ;)
Awesome Bob...gonna make this with the kids :)
Great project bob 🙌🏼🙌🏼
Great project. This is definitely going on the list of things to do. No ILTMS Heavy?!
Brad Dudenhoffer lool. Bob, put that on your todo list
From the ITLMS Heavy it's just a hop, skip, and a jump to the BFITLMS!!
Great project like always!
we did something in my technology 9 class years ago i would recommend adding some thinned wood glue to the tip of your rocket so that it stays together on landing. When i made mine i put several layers of it and some inside the tip. we were going for distance and i won it by getting over 100 feet with that setup working multiple times. We also used an air compressor for air instead of a pressure chamber.
Beautiful. I always wanted such a rocket for myself as a kid. Maybe I'll actually make one some time.
Awesome! Great way to get the kids interested in science too :)
Hey Bob. that is AWESOME!!!!! We went to our MakerFaire in Milwaukee and they had something very similar. They let us build our rockets with foam pipe insulation and duct tape. Kids thought this was a blast. I have to make one....thanks for making this video!
Good stuff Bob.
Now that's a cool project..
Wowwww your projects ara fantastic!!!
Like it!!!
We had a rocket like this as kids and had a lot of fun with it!
Liked the moment: "... and just make everything bigger" :D
That was the bomb. Thanks.
Very cool project!
Nice project
This video makes me happy. Thanks!!
This project, I’m putting high on the going-to-do list.
I didn't know you could link 9V batteries together like that! Genius!
Go bob daddy of the year love ur channel it’s addictive lol
Good project! The launch vehicle is steep, children liked it!
I love the little Falcon Heavy reference with the little cat emoji!!
Looks like you had as much fun as your kids. :-) The car on the rocket killed me. LOL
That is great. I'm definitely going to build that for me and my 6 year old son. He will love it ... and so will I. Thanks!
AWESOME YOU ROCK!!!!!
Man, your kids must think they have the coolest dad! Great build!
Fun! I know the kids had a blast with that!
Just in TIME for the weekend.
2:57 ultra magnus is just chilling on the shelf . By the way , great build bob ! I would definitely try to make it . Hope my nephews enjoy them
Another great project! Ill have to build one of these why my boy gets a little older. I'm sure he will love it!
Cool stuff! Glad you decided to go with the larger pipe with reducers.
Keep posting these awesomenesses of yours! ;)
You're such a badass. I googled an idea I had, and ended up back here on your channel like always.
Im just sayin...That looks like lots of fun!
Awesome
It was awesome!
Great vid. I made one of these a couple of years ago.i had 2 upgrades that you could add to your pretty easily. I made a switch on a box with the button that turned on an led when the system was live. That helps for a little safety too. It also made my daughter feel cool when she powered on the system. She would yell " system live, stand back." Also, I made the barrel coupler with threaded couplings so I could swap out the barrel. For Halloween I put a 2 inch barrel on and fired candy up into the air with a wadding of paper towels to for the seal. Great vid.
That rocket *blew* me away
Cool idea
Very cool man!
Keep up the good work
Can't wait for my kids to be old enough to make this with them!
Great video! I did something similar to this at my school except instead of having a sprinkler valve, we have to release the pressure manually with a lever. It would have been helpful to have one of those. I got a good laugh out of the sponsor playing over the looped footage of you using the bike pump 😂.
I like the mini roadster you had on the one rocket..
Wow so cool Bob :) Another job well done.
Looks like fun
Mac valves are awesome fun and cheap
Hello to you. Good work,I don't speak your languages but I admire your work .
Good dad-ing. "...Everything Bigger." Always a good idea.
Great!
"x-wing" and the red car taped to the rocket! Genius!
I really like the new video format, great work, keep it up❤.
Anyone else notice the tiny Tesla on the rocket! LOL Pretty sweet Bob - my kids are going to love this!
Love your vid keep up the awesome work
6:28 LOL that little car.... #SpaceBob
Love the project, Bob! Nice execution and works good!
You have unfairly raised the dad bar sir
