When I was in secondary school I learned about Van de Graaff. What I know about Van de Graaff is a metal sphere that make someone’s hair stand on and the sphere is known as Van de Graaff generator.

This magic wand was created based on the theory of Van de Graaff. This battery powered wand features a mini Van de Graaff generator inside that can causes the 3D mylar shapes to levitate at your command. It’s really cool!
