How static electricity can be dangerous and how we can prevent this?
Exploring Static Electricity
Explores static electricity with wool, balloons, plastic straws and more.
How Do Touchscreens Work?
Your fingertip and the screen act like the plates of a capacitor and the tiny difference in charge between them is used by the computer in the appliance to trigger a response.
Static Electricity Fun
See what 500,000 volts of static can do. This experiment uses a van De Graaff electrostatic generator.
