Static Electricity from Car Seat Materials
Medium
Can the material of your car seat create a dangerous spark at a gas station? Static buildup from clothing and seats has caused real fires during refueling.
You rub a balloon against four materials:
- cotton
- polyester
- nylon
- hair
Then you see how many tiny paper pieces the balloon picks up from a PVC seat and a leather seat. More paper means a stronger static charge. You discover which material and seat combination creates the most static.
Hypothesis
The hypothesis is that leather car seats produce more static electricity than PVC seats.
Method & Materials
You will test different materials by rubbing a balloon on them and then using the balloon to pick up pieces of paper from a car seat.
You will need a balloon, a copper plate, a ground connection, a jumper wire with crocodile clips, a PVC car seat, a leather car seat, a polyester cloth, a cotton cloth, a nylon cloth, a wig, a flat tray, a ruler, a large sheet of paper, and a paper knife.

The results showed that the balloon rubbed against the hair collected the most number paper pieces from the PVC car seat as well as the leather seat. Between the two seats, the balloon picked up more pieces of paper from the leather seat. This observation stands out as it proves that leather car seats produce more static electricity than PVC seats.
Why do this project?
This science project is interesting and unique because it explores the dangers of static electricity at gas stations, which is an important safety issue.
Also Consider
Experiment variations to consider include using a comb instead of a balloon and testing different car seat materials (e.g. seats made from cloth or Vinyl).
