Experimental DIY Molotov bubble lamp type thing.

A slightly dubious attempt to test a DIY bubble lamp made out of a repurposed candle lamp filled with (combustible) acetone, an improvised vacuum drawing arrangement using a syringe and floppy bit of silicone tubing, some salt and four quarter watt resistors resined to the base of the lamp.
It works, but it's hard to maintain the vacuum without a proper seal, and the fine salt and acetone seem to result in violent explosive bursts of vapour. At one point with enough vacuum and a thin layer of salt I got fairly decent continuous bubbling.
