Static Electric Levitating Wing Experiment
An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 7 to 9.
Materials Needed
- • Ultra-thin plastic produce bag (1 bag)
- • PVC pipe segment (approx. 40 cm) or 1 latex balloon (1 unit)
- • 100% wool cloth or microfiber drying towel (1 cloth)
- • Scissors (1 pair)
Pro Tips
- → Use ultra-thin, lightweight produce bags from the grocery store rather than thick plastic bags.
- → Cut a narrow 1-inch ring from the bag; when charged, it repels itself into an open circular hoop.
- → Charge both the PVC pipe and the plastic ring with the same wool cloth so they both take on negative charges, causing them to repel each other.
Safety First
Perform in dry indoor air; high humidity dissipates static charges quickly.

Step-by-Step Instructions
Step 1
Flatten an ultra-thin plastic produce bag and cut a 2-centimeter-wide ring cross-section from the middle.
Step 2
Rub the plastic ring vigorously against a wool sweater or microfiber cloth for 15 seconds to coat it with static charge.
Step 3
Rub a 40 cm PVC pipe (or inflated balloon) with the same wool cloth for 15 seconds to charge it negatively.
Step 4
Toss the plastic ring into the air and hold the PVC pipe directly beneath it: the electrostatic force repels the ring, keeping it levitating in mid-air.
