The Van de Graaff
Generator—
Multi-Demonstration Kit
By: The Flinn Staff
This kit contains five safe
and “electrifying” demonstrations
your students! The included
detailed safety information
will help you reduce the risk
of accidental shocks.
• Let the Sparks Fly!—
Observe flying sparks as
a discharge electrode is
brought near the dome of the generator.
• What a Blast!—Foam peanuts shoot right out of a plastic cup.
• Flying Saucers!—Aluminum pans fly off the dome due to repulsive electric forces.
• A Hair-Raising Experience!—Use a static “hair” wand to illustrate the classic hairraising
• The Neon Wand!—Be amazed as a neon wand glows bright orange when brought
into the electric field surrounding the Van de Graaff generator.
Kit provides vital safety information along with detailed teacher instructions and a
reproducible student worksheet.
Note: A Van de Graaff generator and discharge electrode are required and available
separately.

Discharge
Electrode
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 the base
of your generator. Store the discharge electrode on its sturdy
cast iron tripod base.
This unit does not include a base.

Build a Mini Van de Graaff
Generator—Student
Laboratory Kit
By: The Flinn Staff
The mini Van de Graaff generator stands
about 18 cm tall and will generate enough
charge to make the hair on a piece of
animal fur stand up! As the static charge
on the generator increases, various materials
such as small paper pieces and tinsel
can also be sent flying off its dome. A
very small shock may even be felt when
a fingertip is brought near the generator.
Includes detailed instructions, Teacher
Notes and student activity sheets.
Complete complete for eight student
groups. A 3-volt power supply is required
but not included.
Electric Plume
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 acquire a charge, even though they
are normally thought of as insulators or
non-conductors. As the charge builds, the
ribbons will stand away from the dome and
from each other.

Wimshurst Static Machine
Produce high voltage during your electrostatic
demonstrations. The rapidly
spinning plates on
the Wimshurst machine add a level of motion
and excitement to the electrostatic charges
being produced. The electrostatic charges are
collected and discharged across the spark gap
consisting of two balls mounted on metal rods.
The spark length can be safely changed by
adjusting the rods using the insulated ebonite
handles. With the two Leyden jars in place,
sparks of over two inches can be created.
Without the Leyden jars in the circuit a rapid succession of low energy sparks is
produced. A very durable unit with unbreakable plastic static plates. Comes complete
with user guide and suggested experiments.
