Charging by Rubbing Simulation

1. Click "Start Rubbing" to charge the ballpen refill

2. Click "Bring Near Paper" to see the effect

3. Click "Reset" to start over

Science: Rubbing creates static electricity through the triboelectric effect. The polythene gives up electrons to the refill, making it negatively charged.

Triboelectric Series:
Polythene is higher in the triboelectric series and loses electrons to the refill.
Electrons move from the polythene to the refill, making the refill negatively charged.
