Use “Fun Fly Stick” to charge up conductive sheet.
Mylar strands align with electric field.
Place support rods together to form cylinder. Electric field of cylinder points outward radially.

Developed by NASA Scientist Steve Papell in the 1960’s, Ferrofluid is a colloidal liquid made of paramagnetic nano particles. When subjected to a magnetic field, the nanoparticles form regular patterns of peaks and valleys.
For an interesting list of modern applications see:https://en.wikipedia.org/wiki/Ferrofluid

- Principle: Static electricity is cool.

generator in plastic containers.
Some ideas for experiments beyond the typical shock-myself-and-my-students:
- Bend a paper clip into an L shape and tape it to the charged sphere to create
an ion gun; point the paper clip at the palm of your hand to feel the “ion
wind”. Point the paper clip at your shirt to charge your shirt up- after
30 seconds shirt should begin sticking to your chest.
- Place a cup of styrofoam peanuts, or a stack of styro or aluminum plates
on top of the sphere, turn on generator and watch stuff fly.
- Dim the room lights, touch one end of a fluorescent bulb to the charged
sphere and the other end of the bulb to the small discharging sphere. Bulb
- Using a squirt gun shoot a stream of water past the charged sphere; water
should ionize and stream will disperse.
