Wow! Bringing back memories ... haven't seen one of these in 40 years .. fond memories of a kid in Cub Scouts having all sorts of fun! Thanks for sharing 🇨🇦

Wow! I am the original creator of the 3D printed pop pop boat. It was 7 years ago since I published that video and put the files on Thingiverse. I was 19 at the time and just bought my first 3D printer. I have been a fan of your channel for a long time so it is really cool to see my design featured in your video.

Bath time couldn't be more fun. Good fun project and thank you for a clear making of the boat.

I liked the idea of trying to press-fit parts together instead of having to traditionally glue or solder them, like your attempt with the aluminum diaphragm.

Yes we did that pop boat long time ago also, but now it is up to another level - have grandchildren as an excuse, but my wife tell me - Jan, are going back to childhood? I am 72 now and still having a tube bath... life is the ability to play and be amazed by the physics... The boat is plopping around in the foam.

I found sciencetoymaker when I was a kid and made one of these. Very nostalgic.

This is wonderful, I loved this little boats when I was a child, I will definitely build one with my nephew!

Thanks for your very detailed project! Will make one for my grandchildren!

Cool, sixty years ago, I had a little boat like this! Thanks a lot for sharing.

This video made me smile for sixteen minutes straight. Thank you!

Wow! That 16 minutes flew by... cool build, cool video.

Pretty clever little toy👍 I’ve never seen these before🙂

Great I love this myfordboy I made one of these as well when I was a kid. I would love to see you make a cotton reel tank ok I know this is not anything to do with metal work but I would love to see your take on how you used to make a cotton reel tank.

Amazing toy boat & awesome technice, beautifully defined.

Just have to make one! TFS, GB :)

A good fun project... enjoyable viewing, thank you

Maybe it is pretensious, what I write now, but it is one of the greatest things I've ever seen on KZfaq. ;)

Very cool boats...:)

I wonder how big of a pop pop boat could be made? I just watched Steve Mould's explanation on how these boats work. I am now wondering where tipping points is before the boat is too big to work.

if at your age you have the spirit to play with the boats in the bathtub you are younger than many teenagers today. I admire you

I LOVE IT IS VERY GOOD AND IT LOCS HARD TO MAKE

Very cool.

Works without valves? Clever

Brilliant 👍👍👍 I remember playing about with these when I was a kid. I think they used a single loop of small copper pipe. Cheers, Alan.

Such great filming I could hear you digesting your breakfast 🤩 never know when the pants demons going to strike,thanks for the wonderful containt👍👍

Great little project but very predictable that the ABS frame components would fail due to heat on the final version. It does make me wonder at times when i see the poor understanding of what material choices are fit for the job and those that are predictably not so.

ok, so how about take the hemispherical bottom from 2 cans, cut at 3/4 inch vertical and wrap a 2.5 inch strap around the perimeter, seal with hi temp adhesive, cut tabs in the wrap piece and fold over to hold the halves in place. can add 1/8 pop rivets to cinch it all up while the glue dries. cut thin sheet aluminum to replace the plastic piece that melted, use phenolic washers to reduce the heat transfer.

NICE

lol! ok thats cute :)

Wow, I turned it off it was boring
