True or False, Lighting is a form of static electricity.

• True
• False

What makes a charged balloon stick to the wall?

• Protons transferred to the balloon when it was rubbed on metal.

• Electrons on the surface of the balloon push away electrons in the wall, leaving a positively charged area.

• The rubber in the balloon has a magnetic field that pulls on the wood in the wall.

• Electricity in the balloon creates a magnetic field that attracts the metal in the wall.
