Superheated steam bottle explosion

This is a bottle bomb I devised that uses only water to produce an explosion. A 850W heating element was fed into a bottle containing 375ml water, and the top epoxied shut.

I set up a mock computer desk around it using old computer junk, and turned on the heater, no one in the room of course. After 5min 40sec, the epoxy cap softened and sprung a leak, spinning the bottle around and causing it to crack. The superheated water, at around 190 degrees C (350F), flash boiled into steam, blowing away most of the stuff on the desk.

What was that blue and orange flash right before it exploded at 1:25 (blue, followed by orange) and 1:26 when a geyser of steam exploded everywhere.

The flash was caused by the AC power connections to the heater short circuiting. They were connected straight to the wall socket, so there's quite a bit of power there to make a spark. If you look at the beginning of the video, you can see the bare wires coming out the top of the bottle, soldered onto a cord. When the bottle fell over and spun around, those touched and shorted out.

1:39 the slow motion version of the sound reminded me of the last moments of the sinking of the titanic in the 1953 movie. it included a bang. this is what sound engineers must have done back then haha

@bruchpilotxxl short circuit of heater in the bottle..it was still connected to power

[peppersdog1]

do not under estimate the power of steam

TEA TIME!!
