Some history on Pop Pop boats you look at this Wikipedia link on the subject http://en.wikipedia.org/wiki/Pop_pop_boat 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.

Daryl Foster devotes his channel to Putt Putt boats and here is the first one on his channel also back in 2009 https://ai-tube.com/videoai/4Gmujsvg6rH

Great idea 💡
After the wood dries out you could try putting a couple of coats of Thompson's water seal on it.

I've got an idea in my head for what I think might be a simplified version of the motor for these things... your recent videos have inspired me to try it soon - I'll let you know how it goes if it works (well, even if it doesn't), I'll add a shoutout to your experiments in my video

this one is a popper! maybe use a small alcohol burner made from the tealight tins and a good cotton wick.. I wonder if the tealight tins would make a large enough boiler.. whatever that wood is it would make great wax wood for fire starting, put the dry wood in hot liquid wax until it stops bubbling and sinks..viola..wax impregnated wood.. I had some scraps set out to do just that and it rained for 24hrs !thr weather forecasters were a bit off on the warm and sunny forecast...imagine that !
Always amazes me how well these things run with so little to them.
