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!
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.
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.
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
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!
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!!!!
Can you tell me what the three step down pieces are called between the timeframe of :336 to 3:42? I am looking to make this same type with a large PVC diameter, but need to find a way to step it down to my 1 inch sprinkler valve.
What pressure were you filling up to? I know you're looking for max power, but depending on the pressure, it would be cool to do a two tank system with a reducer valve so you could get multiple shots without having to pump every time.
I started to build one this weekend with my kids, with a slightly altered design. During the pressure test one of the fittings failed at 60psi. Please be careful as it was a fairly kinetic event. No one injured and only some pipe broken, but something to be aware of.
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!
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.
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!
What a cool project. What kind of PVC did you use? I remember having to track down the pressure rated stuff when I built a spud cannon a few years ago. Did you have to do that or could I just build one of these with schedule 40 from the home center?
I used schedule 40 since we're just using a bike pump. That puts a built in limit of what you can physically add to it. If you're using a compressor, get the right pipes for sure. 👍🏼
What if you used this to launch a rocket that also had an engine to slingshot it higher? Maybe an altitude switch to ignite after its shot a couple hundred feet?
QUICK PRO TIP. From a cub scout dad that has experimented with this type of device. If you put a penny or two under the nose cone/top of the fuselage and launch it without fins. They will go insanely high, you will lose sight of them. (Optimally 40psi in the chamber)
I built a similar one with twin storage tanks and i powered the sprinkler solenoid with a 9volt battery in a handle with the fire button on one end. Kids love it.
Can you make video on soldering and some tips for using a soldering station.I have recently bought a soldering station but I am have trouble using it. I can tell this is some quality content!
funny thing is the writing on the bigger pipe said that its not for pressure. I've got an idea for you, why don't you build a bigger bike pump? Always inspiring, great work!
Are you sure it needs 24v? I use mine consistently with 12v and have even used it temporarily with 9v, though 9v batteries seem to discharge quickly and heat up.
if you put the valve in the middle of the air chamber you will get more height, without increasing the size of the air chamber. also, if you use a butterfly valve you will also get more height.
I have looked through the comments and didn't see what I was needing, I apologize for a dup question if it has been asked. I see the 4" PVC with the reducer down to what looks like a 2" PVC, then a connector down to 1". On the other side, 1" coming out of the valve, then I see a metal threaded piece, that is that piece? Very cool project and I plan to make it this week for the grandboys! Kent
Cool project. Safety note. 4" schedule 40 only has a working pressure of 133psi. With a bicycle pump your probably fine but you could get close. Now burst pressure is higher than you could get with that pump BUT PVC is not UV stable so having out in the sunlight is eventually going to greatly reduce it's burst strength. This is compressed gas and PVC shatters like glass when it goes. So I would pain it as a general precaution. There was a time when a bunch of shops thought they would save some green and plumb their are lines with PVC. Then a few years later they would explode and send everyone to the hospital. With a hand pump I doubt your anywhere close to hazardous, this is more for a viewer who things they should supercharge it using CO2 or a high pressure pump.
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.
Our church made a couple of these for a VBS. Work great! Then the youth loaded nerf darts in them. The high pressure wound up splitting the nerf darts open! Tons of fun! Great build, Bob!
How much pressure are you putting into that pipe and what are the approximate corresponding rocket heights? I'm concerned that we'll have to pump for 5 minutes for each rocket blast.
I'll answer my own question for the benefit of others. I just built one of these today...almost identical to Bob's...4" PVC pressure cylinder, 1" sprinkler diaphragm valve, 1/2" low pressure launch tube, bicycle pump powering the whole works. For the rockets I'm using "thick" paper which is something close to card-stock. It's heavier than normal printer paper but it will still pass through a laser printer just fine. At about 18-20 PSI a thick paper rocket will launch about 20-30 feet into the air. I made a rocket out of normal weight printer paper and tried to launch it using 30 PSI and the paper literally exploded without leaving the launch tube. I have not tried a thick paper at higher PSI yet but that will come soon. One other note, I had a problem attaching the nose cones so I cut them out slightly over-sized and used hot glue all around the rim of the cone to seal it to the rocket tube. That works really well. Oh...and with the bicycle pump I'm using (again, almost identical to Bob's) it only takes 30-45 seconds of pumping to get up to about 20 PSI...not long at all.
What pressure are you pumping up to? Also, mine doesn't sound like a snap when it launches, it kinda sounds like a blow horn.. do you think I did something wrong?
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!!!!!!
Loved the subtle SpaceX reference at 6:29
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
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.
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!!
Really lovely , I am very happy to see your kids are happy with that 😍
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
Nice touch with the car on the front of the rocket :D
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!
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!!!!
The coolest dad ever !!!
The intro and your reaction to the rocket going off alone was pure gold
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
Anyone else notice the tiny Tesla on the rocket! LOL Pretty sweet Bob - my kids are going to love this!
Can you tell me what the three step down pieces are called between the timeframe of :336 to 3:42? I am looking to make this same type with a large PVC diameter, but need to find a way to step it down to my 1 inch sprinkler valve.
What pressure were you filling up to? I know you're looking for max power, but depending on the pressure, it would be cool to do a two tank system with a reducer valve so you could get multiple shots without having to pump every time.
PVC isn't made to hold a ton of pressure so I was limiting it to what the bike pump could put out.
I started to build one this weekend with my kids, with a slightly altered design. During the pressure test one of the fittings failed at 60psi. Please be careful as it was a fairly kinetic event. No one injured and only some pipe broken, but something to be aware of.
Hey Bob this has nothing to do with the video but could you tell me the dimensions of your shop? I want a shop similar in size to yours.
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!
I didn't know you could link 9V batteries together like that! Genius!
Good project! The launch vehicle is steep, children liked it!
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.
The little red car on the nosecone was a great touch!
award for 'cool dad of the year' goes to...
love this! keep up the great work!
That kid who put the nerf dart in the launcher will win so many future nerf wars
Loved the bloopers
Your kids are so lucky to have you as a dad, Bob!
I can just see when they get into nerf they will have the best tech lmao!
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!
2 months for 99 cents? I'm in. Thanks Bob.
Definition of a great dad!
Complete with an ILTMS Roadster ;-)
i saw that too, nice touch bob! :)
Subtle but important detail 🚗
Skillshare is awesome :) And so is this project. Keep it up!
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!
Bob's thinking..."I need to make this bigger...much bigger..." That. Was. Cool! Love the vids with your kids!
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
You have unfairly raised the dad bar sir
I love the little Falcon Heavy reference with the little cat emoji!!
Nice usage of what I assume are leftovers from the scrapped Transformers cannon.
You're an awesome dad
Awesome! Great way to get the kids interested in science too :)
You really are an awesome Dad! Keep up!
"x-wing" and the red car taped to the rocket! Genius!
Man, your kids must think they have the coolest dad! Great build!
Nice project ! Good mix of wood, electronics, metal and air pressure... And nice Music also !
If you have the right fitting for an air compressor you can get higher pressure and shoot the rockets way higher
This 'Tesla' on the end of the rocket was a nice touch. =D
Awesome video, thanks for this! Any way we can get an updated link for the pdf? Not working anymore.
Fun! I know the kids had a blast with that!
What a cool project. What kind of PVC did you use? I remember having to track down the pressure rated stuff when I built a spud cannon a few years ago. Did you have to do that or could I just build one of these with schedule 40 from the home center?
I used schedule 40 since we're just using a bike pump. That puts a built in limit of what you can physically add to it. If you're using a compressor, get the right pipes for sure. 👍🏼
Awesome. Thanks!
Im just sayin...That looks like lots of fun!
What great memories your creating with the kids!
Love the little roadster you put there! ;)
What if you used this to launch a rocket that also had an engine to slingshot it higher?
Maybe an altitude switch to ignite after its shot a couple hundred feet?
Looks like a lot of fun for the kids!
Go bob daddy of the year love ur channel it’s addictive lol
Ahah the little car on the top of the paper rocket ! Space X power !!!
Awesome video as always :)
QUICK PRO TIP. From a cub scout dad that has experimented with this type of device.
If you put a penny or two under the nose cone/top of the fuselage and launch it without fins. They will go insanely high, you will lose sight of them. (Optimally 40psi in the chamber)
I built a similar one with twin storage tanks and i powered the sprinkler solenoid with a 9volt battery in a handle with the fire button on one end. Kids love it.
I also use a single 9v battery for my valve. Makes it super simple.
Love it when you include your kids in the video. And great project too.
I like the little Tesla on one of the rockets
Can you make video on soldering and some tips for using a soldering station.I have recently bought a soldering station but I am have trouble using it.
I can tell this is some quality content!
funny thing is the writing on the bigger pipe said that its not for pressure. I've got an idea for you, why don't you build a bigger bike pump? Always inspiring, great work!
I was wondering how you were launching them so high with the small setup. Then 3:25 happened.
Watching this brings back memories I had in middle school when in my science class I believe, when we all had to make rockets. Mine went the highest.
Mine busted my teacher's window when a fin fell off, but I got the most PSI in mine
Did you hook it up to a car air compressor to push as much psi as possible to see how high a rocket will go?
What a fun project. Can you launch those little plastic guys with the plastic parachute and watch them float down?
Oooohhh, that's a cool idea!
0:49 is that a CNC router on the background ? 0.0
Bob u must be like the best dad ever with these epic iltms toys and games
I like how the pvc pipe explicitly states "not for pressure" :D
Looks like you had as much fun as your kids. :-) The car on the rocket killed me. LOL
Are you sure it needs 24v? I use mine consistently with 12v and have even used it temporarily with 9v, though 9v batteries seem to discharge quickly and heat up.
I wonder if you could use this to add extra force in a conventional rocket?
Yes, I know PVC isn't supposed to used as a pressure vessel, but that 4 inch pipe os rated at over 130 psi, so chill. And First.
Good dad-ing. "...Everything Bigger." Always a good idea.
Hello to you. Good work,I don't speak your languages but I admire your work .
Dad of the Year!
if you put the valve in the middle of the air chamber you will get more height, without increasing the size of the air chamber. also, if you use a butterfly valve you will also get more height.
ILTMS Space Division sounds pretty cool :)
Yes!!
I like the little musk homage @ 6:28

KnKinCabot Kent looks like it’s reduced down to 1/2” cpvc since a nerf dart fit in it

Is there a way to possibly make this to fit into a mandalorian jet pack to launch a foam rocket ?
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!
Great job! Now comes the parachute assembly in a double stage.
He is insane. And that is what I like about him!
Our church made a couple of these for a VBS. Work great! Then the youth loaded nerf darts in them. The high pressure wound up splitting the nerf darts open! Tons of fun! Great build, Bob!
Yeah, they work GREAT with Nerf darts ;) That's my favorite use so far !
You manage to 'forcefully expand' any yet?
What a great way to spend time with children....
which has more potential to go higher .. Water powered or just air powered rocket ??
Can't wait for my kids to be old enough to make this with them!
Very cool! I bet the Air Burst Rockets would work great with this.
Definitely gonna be making this for my kids!!!
