Synopsis
Create your own lightning with these time-tested devices that have delighted students for decades! Named after the inventor Van de Graaf, a German physicist, this machine produces low-amperage static electricity that can be shocking but perfectly safe. Two different pulleys with 2 neoprene belts inside a 1¾ plastic column create and carry static charge up to the 7 polished aluminum collector globe. You can draw out this static charge in a burst of lightning, sparks, or you can even set each hair on your head on end! It's an incredible display! The entire unit is 18 tall and runs on 110VAC and includes a ground clip for discharge wands. Our comprehensive instruction book tells you how to raise hair, produce lightning and electric wind, experiment with St. Elmo's fire or electrostatic attraction and repulsion. For a stunning display use the matching discharge wand with your VG200 and watch the sparks fly between the two globes! If you're looking for a really neat experience and want to learn the basics at the same time, the Van deGraaf generator is for you. This version is factory assembled and tested so you can just plug it in and make the action happen! If 200 kV isn't enough zap for you, check out our VG400 - 400 kV Van deGraaf Generator! (So we got these in, our techs set one up, and they called me to make my hair stand up on end....wait, my hair fell out when I was 22!)
