What happens when you take a CD, microwave it for 5 seconds, and then put it on a Tesla coil? 8O
Great stuff. And it's not the only thing he zaps on his site...
Warning: Don't try this at home unless you're a qualified electrical engineer! Tesla coils and microwaved CDs can be very, very dangerous if not handled properly. (Actually, they can also be very dangerous even if you handle them properly...)
