Tesla coils are those electrical devices with loops of coil around a tube and a solid metal dome on top that spark when electrical current is fed into them.  You’ve probably seen one either in a movie, or the Museum of Science in Boston has a giant one they use to simulate lightning.

Here’s some video and photos of neat things to do with small, home-sized (**But still very dangerous**) tesla coils.
