Have you ever taken off a wool sweater and heard tiny snaps? Or rubbed a balloon on your hair and made it stand up? That’s static electricity — invisible force at your fingertips!
What You’ll Need
🎈 A balloon (blown up)
👕 A wool sweater or your hair
💧 A thin stream of water from a tap
🧂 Tiny bits of paper or salt
✏️ Empty soda can
Experiments to Try
1️⃣ Bend Water With Magic
Turn the tap on so a thin stream of water flows. Rub the balloon on your hair for 10 seconds. Slowly move the balloon close to the water stream — without touching it! The water bends toward the balloon! 🤯
2️⃣ Levitate Paper
Tear paper into tiny pieces. Rub the balloon on your sweater. Hold the balloon over the paper bits — they jump up and stick to it!
3️⃣ Roll a Soda Can Without Touching It
Place an empty soda can on its side on a smooth floor. Rub the balloon on your hair. Hold the balloon near the can without touching. The can rolls toward the balloon!
What’s Happening?
Everything is made of tiny particles called atoms. Atoms contain electrons, which carry a negative charge.
When you rub the balloon on your hair, you transfer electrons from your hair to the balloon. Now the balloon has extra negative charge.
Negative attracts positive. So the negatively charged balloon pulls on the positively charged parts of water, paper, and cans!
Why Static Makes Hair Stand Up
When your hair has the same charge (all negative), the hairs repel each other — pushing apart and standing up! That’s why your hair goes wild after the balloon trick.
Real-life static: lightning is HUGE static electricity from clouds! ⚡
