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.
Each Tuesday is EducationTuesday here at Adafruit! Be sure to check out our posts about educators and all things STEM. Adafruit supports our educators and loves to spread the good word about educational STEM innovations!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
