How does it work?

It's very easy to create static electricity - just rub two different materials together! Everyone has experienced static electricity, perhaps going down a slide, jumping on a trampoline or by rubbing a balloon on your head. The Van Der Graaf generator creates static electricity by rotating a rubber (silicone) belt, around a metal rod. When these two materials rub against each other they build up lots of positive charge.

When you place your hand on the metal dome, it stands up. The positive charges that have built up from all that rubbing, and are now flowing through your hand, your arm, neck, head and hair. Your head and each strand of hair become positively charged, because they're all the same charge they REPEL, causing your hair to stand up!
