Have you ever noticed your hair standing out on a dry day, or how a fuzzy fleece blanket can make sparks if you rub two sections of the blanket together in the dark? Both of these things are caused by electricity—which also runs as current through wires behind light switches and electrical outlets. But the form of electricity that causes hair to stand up, known as static electricity, is much weaker (though strong enough that a buildup of static electricity can cause a slightly painful shock if you touch the right surface).
Because it’s weaker, static electricity doesn’t work as well to power light bulbs or appliances, but you can make it do some surprising things around the house.
