Back when a schoolkid, I had some fun by placing an electric arc right 
next to a microscope slide. It melts a small puddle, then the arc just 
vanishes since the molten glass is nicely conductive.

All goes well until the whole explodes due to thermal stresses. Then there 
is the not-so-fun task of collecting glass from all over the room.
