High voltage is not only fun to watch, there are quite a few projects that you can build yourself with surprisingly little equipment or time!  Here’s a quick list of all the wild things possible with a few hundred Kilovolts.

• You too can shrink coins – These little coins are reminiscent of shrinkey-dinks, but shrink in 40 millionths of a second!
• PowerLabs – Tesla Coils, Marx Generators, Plasma Globes and more!
• Miniature Coil Gun – Blow your friends away (not really..) with this sweet schematic on building your own Mini Coil Gun.
• Portable Coil Gun – Made from a single disposable camera, this gun can shoot a nail 20 feet!
• High Voltage Guide – Almost all necessary information on getting started with HV at home.  Sweet!

And speaking of fun to watch..

• 500KV opening switch failure
• Australian HV hacker makes HUGE Tesla coils
• 180KV Marx Generator
• Cars don’t like homemade lightning..
• 2.2 Megavolt Lichtenberg Figures in acrylic

And lastly, we bring you the instantaneous death of a watermelon.

Remember, high voltage is dangerous!  But man is it fun to play with!
