A neon screwdriver is destroyed - without the use of electricity.
Neon screwdrivers are unreliable and this particular example is very poorly constructed, featuring a large hole in the end where water and other contaminants can enter.
Here, a mixture of certain chemicals is placed into the end hole, and then some water is thrown in. The actual specifics of the chemicals used will be classified.
Chemicals destroy plastic screwdrivers very effetively.
