Their large VandeGraaff kit is $299.95. 35cm globe, 90cm tall, 400KV,
120V motor.
Belts can be obtained separately! 2" x 23". $17.00 It doesn't say so in
the catalog, but these are probably the same heavy grey neoprene material
I received with their original kit in '88. Also, 14" globe, $80,
7" globe, $25
This company also sells various physics devices (dynamics carts,
microprocessor timer, electrostatics accessories, density kits, force
tables, etc.
Interesting plans: fluxgate magnetometer $4.95, experiments in high
vacuum, $6.95, others.
