How to Build a Van de Graaff Generator

While it has a few flaws, on a good day this homemade VDG can produce around 200,000 volts of static electricity. Join me as I walk you through how I made this fun and mostly impractical project. If you do decide to make or use one of these generators, keep in mind that while they are mostly safe, there's a chance they can pose some danger to people with heart conditions. Also know that the high voltage sparks WILL fry electronics such as cell phones and watches.
