Static electricity discharge in carsFeatured science projectScience project video

Conclusion

The hypothesis that  leather car seats  produces more static electricity compared to fabric seats is proven to be true.

The static charge present on surfaces is higher during periods of low humidity. They pose a great danger at gas stations where flammable gases are constantly present. A sudden spark caused by the rubbing of a person’s clothing against the car seat while the person gets out of the car could be extremely disastrous.

Also consider

The science fair project can perhaps be repeated using a comb instead of a balloon.

Would different car seat materials (eg. seats made from cloth or Vinyl or PVC) produce different results?Reference:
