How is static electricity generated?
Today there is a fun science game inside the bubble spaceship, the little crew in front of a plastic bottle, above a flat straw, the green bubble gently waved and did not touch the straw, but the straw is automatically turned around, how is this? Smart children must have thought, this is the effect of static electricity. So how does static electricity come about? Is produced by friction, today we will do a small experiment of friction electrostatic, the students come to study together!
The plastic stick rubbed with a towel can generate static electricity to hold the balloon
Children, come and study together!
