I recently made a steam boat. The instructions, at
http://www.sciencetoymaker.org/boat/makeBoat4_07.htm, called it a pop-pop boat, but it runs
fundamentally on steam. First, I made a "boiler" from an aluminium soda can, cut and folded to the correct shape and size, with two straws sticking out. I then sealed the boiler with epoxy glue and silicone sealant. While the silicone dried, I made the hull of the boat with a milk carton, cut and folded. Once the silicone on the boiler dried, I stuck the straws that were poking out of the boiler through a hole that I had cut in the hull and
bent them back under. I then glued the straws and boiler in place with a cool-melt hot glue gun. Now steam engines are external combustion engines, so for the "external combustion", I added a candleholder I had made to fit quarter birthday candles. On the day I finished it, I tried it out in the bathtub. On the first run, it worked, altough not very well, but the second try was amazing. The funny thing is, the day after I tried out my boat, a tin one came in the mail from my uncle and aunty in Australia!

This is a great post! A pop pop boat is a good toy boat that will surely catch the attention of a lot of young boys. You are very ingenious of making one out of milk carton.
