Heart attack bulb

electrolysis bomb.

A stretchy balloon membrane with embedded wires connects to a standard lightbulb base. On application of power, the saltwater inside is electrolysed into H2 and O2.

At a certain level of stretch, the two electrodes are brought into proximity, where they generate a spark between them.

For irresponsible pranking purposes.

       If you add Boron instead of the brime, the light from the bulb would further break down the elements and you would get 2xH2O + B2 -> 2x(1/2HB + O2 )
