@gunfreaksaredead Called a pop pop boat ,They have an English patent and surprise there is mega on them on this marvelous inter weby thing, Maybe make one for grandson for xmas.
The candle flame heats up the water in the copper pipe, and that water "wants" to rise (convection). Half of the copper coil is higher, so the water "wants" to go there more.
This creates a net motion of water from the lower half of the coil to the higher half of the coil. Water isn't really compressible, so some is sucked up one tube, and expelled out the other.
You might guess that this push and pull would counteract, but because of the different length and angle of the pipes it doesn't.
@TheHovishovis It's not to do with convection, the candle heats the water causing it to expand, it expands out of the tubes with a kinetic energy, then the opposite reaction spins the engine.
I can hear blowing lol

Sixty years ago you could buy a tinplate open boat like this . both outlets were at the stern and they would bubble around the bath!

That's a nifty little contraption! It'd be a perfect project for a science class.

for how lond this engine runs? does not the tube get empty of water after some time? or do the vacum created fill it up again?

@87tomify This engine will run as long as the candle is burning. Imagine the candle wax as the 'gasoline' fuel of this engine.

@TheHovishovis The wick burns, not the wax.

@mrfrankincense the wax burns, not the wick! the wick just "sucks" up the wax
