Measuring static electricityFeatured science projectScience project video

Conclusion

The hypothesis that  human hair  has the highest static charge, is proven to be true.

Static electricity is more obviously present on days where humidity is very low. On days of high humidity, the charges are able to discharge through the moisture in the air. Static electricity can be harmful when working with electronics or in the presence of flammable gasses.

Also consider

The experiment can also be done using a comb instead of a balloon.

Try to compare the results by repeating the experiment to see how much the balloon will “pull” or attract a small stream of water flowing from the tap.
