Rub an inflated balloon against dry hair for about 20 seconds, then stick it to a wall, use it to make hair stand up, bend a thin stream of water from a tap, or pick up small bits of torn tissue paper. Static electricity made visible and touchable, not just explained.
What you need
- a balloon
- torn tissue paper (optional)
How to do it
- 1Rub the balloon vigorously against dry hair for about 20 seconds.
- 2"Now stick it to the wall — no tape, just the rub." Let it hold, then peel it off and try again.
- 3Hold the balloon near a very thin, slow stream of water from a tap and watch the stream bend toward it.
- 4Tear tissue paper into small bits and use the charged balloon to pick pieces up without touching them.
Variations
- If hair is too short or wet to build charge: rubbing the balloon on a wool sweater works just as well.
- How it ends: a final "strongest stick" contest — whoever's balloon holds to the wall longest — closes it naturally.
💡 Parent tip
Humid days make static weaker — this works best on a dry day, which is worth knowing before troubleshooting a balloon that 'isn't working.'
What your child develops
- Basic physics — static electricity made tangible instead of abstract
- Cause and effect — friction builds a charge that has a visible, repeatable result
- Hypothesis testing — predicting what the balloon will do to water or paper before trying it
Safety notes
- Popped balloon fragments are a choking hazard for younger siblings nearby.
