Im using coke cans to make a mini steam boat, one that is powered by heating copper wire with a candle. It has to be about 15-18 cm in length, and 4 cm wide. Any tips on how to make it so that it can go very fast? Including tips on how to stick the aluminum together without using glue or rivets or holes of any kind, but it can be folded, and must be inexpensive and light.Some tips on building a mini steam boat?i have never heard of this. i have no idea on how it would even work
