slow, steady stream of water from a faucet
Follow these directions and answer these questions.
- Rub the acetate strip with the tissue paper.
- Bring the strip near a slow stream of running water.
What happened when the strip was brought near the stream?
From your ideas about charges on acetate and vinyl strips, predict what will happen if a charged vinyl strip is brought near the slow stream of water. (Review Unit 4.)
- Test your hypothesis. Rub a vinyl strip with a woolen cloth.
- Bring the charged strip near a slow stream of water.
