A plastic ring made from a very thin grocery store bag and a plastic bat are rubbed with a piece of wool. When the wool rubs either plastic object, electrons are removed from the wool and placed on the plastic leaving the plastic negatively charged. This is called the triboelectric effect, which is the transfer of electric charge from one object to another due to friction. Now that the bat and ring are negatively charged, they repel each other. This allows us to keep the ring floating as long as we keep the bat underneath it properly. 👍 LIKE and SUBSCRIBE for fun science content! ➡️ Follow links at linktr.ee/tamuphysastr #tamu #funny #shortvideo
