It was about 10' tall, with a top electrode sphere 4 feet in diameter. We used to get sparks 4 - 5 feet long. That museum has closed, and the Van de Graaff went to the Whitaker Center, which may or may not still be using it. You might be able to acquire that machine. One of our most popular demonstrations was an accurate depiction of what Ben Franklin did in his famous lightning experiment. -- Bill Moser -----Original Message----- From: Paul Spana <[log in to unmask]> To: ISEN-ASTC-L <[log in to unmask]> Sent: Tue, Aug 3, 2010 5:58 pm Subject: Van de Graaff Generators ISEN-ASTC-L is a service of the Association of Science-Technology Centers ncorporated, a worldwide network of science museums and related institutions. **************************************************************************** Dear friends, Our museum's Education Department is planning a demonstration on lectricity based on the success of their "combustion" shows. Will omeone please recommend a fabricator that creates large Van de Graaff enerators?
