Producing Static Charge – 5A10.00
Electroscopes – 5A10.10
- Rub friction rods PVC pipes and acrylic using fur, silk, or wool to give it a charge.
- Glass rubbed with silk takes on a positive charge as the silk removes electrons from the glass. Amber becomes negatively charged as it strips electrons from fur.
- Hold rod close to the electroscope receiver and watch the leaves separate.
Location: Demo Room
Electric Charge Detector – 5A10.11
- A simple electroscope that detects an electric charge and determines whether it is positive or negative.
- It has a red LED and a transistor.
- The gate wire of the transistor acts as an antennae.
- Bring any statically charged item toward the apparatus and watch the LED.

Static Electricity/Human Powered Light – 5A10.12
- Hold on to the light bulb wires and walk across a carpeted area dragging the feet as you go.
- A charge of static electricity is built up that discharges through the light bulb in the hand.
- If enough charge is generated the bulb will glow in free air.

Electrostatic Charges – “Fun Fly Stick” – 5A10.13
- The “Fun Fly Stick” is like a mini Van de Graaf Generator. It accumulates charge on its shaft.
- This charge can be transferred to a lightweight mylar films.
- The mylar films come in an assortment of different shapes
- Without any contact with the shaft, the mylar stays suspended in air.
