Some history on Pop Pop boats you look at this Wikipedia link on the subject they have been around since at least 1891 when a patent was filed by a Frenchman named Thomas Piot.

Water in the boiler is turned to steam. The steam has a greater volume than the water so it pushes out of the boiler and down the tube. In the tube it cools, condenses and contracts so it is drawn back into the boiler and the process repeats. The action of the steam pushing into the tube pushes the existing water in the tube out the back and that drives the boat forwards. The steam condensing and contracting draws water back into the tube ready for the next push.
If your next question is "why doesn't the boat oscillate backwards and forwards due to this push-pull effect?" try blowing a candle out and then try sucking a candle out and you will see the blow is fairly directional but the suck is not.

Neat idea 💡
Nice one I want to build one 👍🏼
👍 You made me want to build a similar boat. Can you explain me how to curve the pipes without folding/snapping them?
Doc Ink
this one gets a bit of speed, if you have a building supply store nearby, look in the roofing section for flashing, here at least it comes in rolls and small squares, copper, aluminum and galvanized steel

Cut one of the pipes a bit smaller then the other it works better not sure why but it does.

That one works great. It's better than the sealed boiler type although you don't get the pop pop noise. Plus it is fast. I am always full of ideas but just can't get motivated to do it.
I wonder how fast one of them could go if you had a little gas burner instead of the candle? :D
Just had a look at the copper brake pipe on eBay. I used it for my Tesla coils.
Hey granda can you make us a way to make a submarine like light, is it possible tho? Like a lightbulb under water that stays at a constant alt, you know, for romantic effect....xD
How am i this late, i hate the youtube lgorithm, plus, you always upload, how are yoi not on top?
