Van De Graaff Grounding Wands
van de Graaff wand

Portable Wand.
This hand-held wand consists of a 10.5cm diameter highly polished stainless steel sphere mounted on a 40 cm insulated plastic rod. With banana plug and alligator clip to ground most Van de Graaffs. The discharge wand proves a convenient way to discharge the collectors of Van de Graaff generators. This is particularly useful when demonstrating hair-raising. By discharging the collector, the student does not feel a shock when touching the generator. The wand can also be used to draw arcs from the Van de Graaff which can be seen from a distance for an effective demonstration in front of large groups.

Short Wand.
Bring the power of a lightning bolt into your classroom or museum. Here's an easy yet dramatic way to discharge Van de Graaff Generators in full view of the largest crowd. Mounted on a 12" stand to place alongside a Van de Graaff generator at different distances for different discharge sparks, it can also be picked up and used as a handheld wand.

Volta's Hailstorm
Demonstrates the mechanical forces produced by electric charge
leyden jar

When near an active Van de Graaff Generator, the tiny conductive balls inside begin to bounce up and down. It looks as if the pieces are "hailing" as they skitter and rebound. The explanation lies in the fact that the floor and ceiling of the cage become electrically charged. The Van de Graaff builds up a charge by induction as electrons are transferred from the ceiling to the floor. Since the balls lying on the floor are now negatively charged, they are attracted by the positively charged ceiling. But when the balls hit the ceiling, their negative charge is neutralized and they become positively charged instead. Down they fall to the negatively charged floor where they become positively charged upon impact. Back and forth, upwards and down - a veritable "hailstorm in a teapot." This flurry of activity will last as long as the Van de Graaff generator is running.

Volta's Hailstorm includes:

  • Transparent cage mounted on sturdy metal base (9" in diameter)
  • Ball terminal to attract electric charge
  • 12" high, can be seen from a distance
  • Tiny polystyrene balls
  • Instructions with theory

Static Spinner
Works with Van de Graaffs and our Tesla Coils
static spinner

Detect an invisible electric wind from a Van de Graaff with our static spinner. since pointed objects carry a much greater concentration of electric charges than the Van de Graaff's sphere, the spinner will rotate rapidly when in its vicinity. Consists of a metal base, 9" diameter spinner on cone bearings for easy movement, and instructions with theory.

Electric Plume
Demonstrates the forces repulsion by like charges quite dramatically
electric plume

Need a way to demonstrate electrostatic repulsion without a model? This "head of hair" makes a good substitute. Attach the suction cup on the base of the plume to the globe of the Van de Graaff generator. Turn on the machine and watch each strand of "hair" stand away from each other. The reason, of course, is that each strand has the same electric charge and repels its neighbor. With instructions.

A fun accessory for your Van de Graaff generator!

Lightning Leaper
electric plume

Even electricity will follow the path of least resistance. This printed circuit board proves it. It consists of an insulating plate with two binding clips on either end for connecting to a Van de Graaff. On the plate's surface, an incomplete metal path is drawn. Watch the electricity leap over each gap! 10 x 20 cm in size, with two binding clips and instructions.

Wimshurst Machine, Deluxe
electric plume

Unlike many others we have tested, this one works really great!

This device generates static electric charge at higher current (and lower voltage) than the Van de Graaff. It consists of two high resistance plastic discs with equally spaced metal sections. The discs rotate in opposite directions with a hand crank, producing substantial opposite charges which are deposited in the capacitors and on the metal electrodes. You can collect induced charge with the brushes and adjust the electrodes and Leyden Jar capacitors for higher potential. Fully assembled, mounted on plastic base, works right out of the box.
