zombie pop pop boat

Pop Pop boat. An aluminum can, a couple bendy straws, 2 part epoxy, hot melt glue, a styrofoam meat tray, 6 pennies, a couple rubber bands, aluminum foil, and a cut up birthday candle+ 3 hours with or without your kid on a rainy day and you get this pop pop boat... lego zombie added for humor value. Thanks to the genius at http://www.sciencetoymaker.org for the easy to follow instructions, all parts of which are presented in video clips here on youtube!

as far as my understanding goes, it's a rudimentary steam engine... the aluminum can forms the 'engine' which is 'primed' with a little water... when the droplets of water inside are heated by the candle flame, they flash to steam and that pressure blasts through the straws under the boat creating a little thrust. The pressure also causes the metal to flex, making a pop noise as it expels the steam. Another pop noise is created as the metal returns, and at the same time acts as a diaphragm pump, drawing more water through the straws and repriming the engine. Pop pop pop until the candle burns out!

can you describe the construction of the boat.plssssssssssssss

[arcdrummer]

check out the description above, there is a link to the first video in the series that we followed that explains how to make this boat.

[arcdrummer]

@arcdrummer actually, it's below... where it says video responses.

Each putt putt you hear represents one cycle of water getting pulled in then pushed out.

Hey well done on your boat, looks good.

[kevinbusdriver1]

The flame heats a tiny amount of water inside the engine.

As the water heats, it expands and is forced at a great speed down the pipes which thrusts the boat forward.

As the water escapes, so too does the air in the engine. This creates a vacuum that pulls cold water in. This new water is heated and the process is repeated at a very high speed ( 300 times a minute )

The sound is a brass plate welded into the top of the engine moving up and down.
