Circuit
Van de Graaff, Wimshurst or other High Voltage source
Capacitor is metal sheet, plastic, and object
Connect object to circuit ground if not living

User Friendly
Total darkness and High voltage don’t mix
Masking tape - plastic, seethrough, and sticky.
Simple pictures of leaves and flowers
Be careful, lines can show up on final image

Safety
Completely safe
Worst shock is that of a Van de Graaff
Higher risk of arcing

How toBottom plate of capacitor is a thin sheet of metal
Cookie sheets work great
DielectricGlass plates
Binder separators
Paper between dielectric and top plate
Top plate is object to photograph

How toA darkroom is required with photographic paper
Tape black poster board over windows and doors
Safelight
Connect plate to high voltage
Connect object to circuit groundGenerally avoid with living things or people - will give a jolt
Might be required with lower voltages
Play around with exposure time

Objects to PhotographPlants
Leafs, flowers always look great
NecklacesDemonstrates Faraday caging
