Recycled Put Put Steam Boat Pop Pop Candle Engine Powered Working Tin Toy
Cost me £3.37

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.

CUTE ... slow start then BAM!!!! Fine little boat. Raggy
At first it seemed it had little power then bang, it took off. Maybe it was " flooded" : ) I have a putt putt boat in a little box here someplace. Never tried it yet. Not sure where it is either but I will find it. Would like trying to make one also sometime.
