300,000 Volt Hand Driven Van De Graaff Static Electricity Generator
van de Graaff generator

This hand-cranked Van de Graaff with 300 kV potential, including instructions and accessories, is essentially a turn-key operation. Set it on your lab table, invite a volunteer to start cranking, and then demonstrate the static electricity produced. The globe is highly polished and seamless stainless steel 10" in diameter, and the instruction booklet describes a host of experiments as well as explaining in detail how it works.

Several accessories are also included:

  • 40 cm (16") discharge wand with plastic handle
  • Electric whirl
  • Electric plume
  • Point discharge needle

Due to the size and weight, extra shipping may need to be calculated after checkout.

Wimshurst Machine
wimshurst machine This easy-to-use device consists of two high resistance plastic discs 25 cm in diameter with equally spaced metal sections. The discs are supported with two upright posts and rotate in opposite directions through 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, thus generating sparks by lowering the system's capacitance. It is mounted on an attractive wooden base. Instructions include theory and background.

Volta's Hailstorm
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
