Tomorrow and Thursday, we will demonstrate the concept of voltage with the van de Graaff generator, so famous for making your hair stand on end. If you want to try it out, make sure to wash your hair but no styling gel or other goop. My hair is too curly (a sign of geniusness), but even for straight hair, you never know whose hair will do the best.
This photo of Ashlea from a few semesters ago, is one of my favorites.
