Van de Graaff Generator
AP4699
A trouble-free Van de Graaff generator with the features you have been looking for: • Small convenient size (45 cm high, 18 cm sphere). • Rugged moving parts will hold up under continual student use. • Easily dismantled and reassembled for clea...
 
Van de Graaff Generator, 400-kV
AP6476
The most reliable Van de Graaff generator available. This high-quality generator will always deliver the static electricity you need to make demonstrations exciting and vivid. Comb assemblies are rigid and never need adjustment. Large dome produces a...
 
Discharge Electrode
AP5634
Safely discharge your electrostatic generator with this discharge electrode. A polished aluminum 18-cm sphere is mounted on a 40-cm long insulated plastic rod. A long, flexible wire lead has an alligator clip on its free end for easy attachment to th...
 
Discharge Electrode, Economy Choice
AP7111
Safely discharge your electrostatic generator with this discharge electrode. A polished aluminum 18-cm sphere is mounted on a 40-cm long insulated plastic rod. A long, flexible wire lead has an alligator clip on its free end for easy attachment to th...
 
The Van de Graaff Generator - Multi-Demonstration Kit
AP7274
The Van de Graaff generator is a fun and exciting tool to teach students about static electricity and repulsive forces. This kit contains five safe and “electrifying” demonstrations that are sure to WOW your students! The included detailed safety inf...
 
Build a Mini Van de Graaff Generator—Student Kit
AP7277
The Van de Graaff generator offers a hair-raising experience that most students never forget! Having students physically build a mini Van de Graaff generator will be an even more memorable event that will give them a better understanding of the physi...
 
Build a Mini Van de Graaff Generator—Classroom Set
AP7278
The Van de Graaff generator offers a hair-raising experience that most students never forget! Having students physically build a mini Van de Graaff generator will be an even more memorable event that will give them a better understanding of the physi...
 
Static "Hair" Wand
AP6504
Perform the classic Van de Graaff generator hair- charging demonstration with any student in your class. Long, fine hair is no longer necessary thanks to the static “hair” wand. Students hold the wand in one hand as they touch a charging Van de Graaf...
 
Electric Plume
AP5986
This is a vivid demonstration to show that like charges repel one another. The electric plume has a number of colored ribbons attached to a vacuum cup. When the vacuum cup is attached to the top of a Van de Graaff generator, the ribbons will slowly a...
 
Electric Whirl
AP5987
When brought near the dome of a Van de Graaff generator, the whirl spins rapidly in a direction that is away from the sharp points of the whirl arms. The electrons escaping from the Van de Graaff dome to the spokes ionize the air at the sharp points....
 
Flying Ball and Silver Snake
AP5988
Add this spectacular demo to your arsenal of teaching tricks for teaching electrostatics. These “magic wands” behave differently when brought near the dome of a Van de Graaff generator. The metalized ball, when first brought near the dome, is attract...
 
Hollow Sphere
AP5989
Static charges lie only on an outside surface of a charged object and this device dramatically demonstrates it. Charge the sphere by touching it to the dome of a Van de Graaf generator. When a proof plane is touched to the outer surface, a charge wil...
 
Insulating Stand
AP5990
This insulated stand can be used to support electrostatic demonstration devices. It is specially designed to support our Racing Ball Demo AP5994 and Lightning Plate AP5991. The stand is 43 cm high and the base measures 9 cm.
 
Leydon Jar
AP6478
Demonstrate electricity storage using one of the original “batteries.” The perfect apparatus to introduce your students to capacitors and dielectric materials. Charge up the Leydon jar with a Van de Graaff generator, Wimshurst machine or electrophoru...
 
Lightning Plate
AP5991
Create lightning with your Van de Graaf generator. Turn out the lights and connect the lightning plate to your generator. When the lightning is created and the sparks jump across each gap on the lightning plate, your students will be very impressed. ...
 
Neon Wand
AP5675
No plugs nor contact electrodes, yet it still “lights up” when held in a high-voltage field! Your students will be amazed. This neon wand is filled with neon at reduced pressure and will glow a reddish-orange color when you hold it in or ...
 
Proof Plane
AP5993
The proof plane is used to safely transfer electrostatic charge from one body to another. A high quality proof plane uses a spherical shape because a sphere will hold the greatest charge and retain it for the longest time. You will find this spherica...
 
Racing Ball
AP5994
An amazing demonstration of the interaction of electric forces. Place a non-conducting racing ball between the top disk and a connected lower pan. When the Van de Graaff generator is started the ball will dramatically race around the bottom pan as th...
 
Volta's Hailstorm
AP6026
Create a visual hailstorm during your electrostatics unit with this demonstration. When small bits of aluminum foil, pith, or vermiculite are placed in the cylinder and the upper plate is connected to a Van de Graaff generator, the particles will bou...
