An interesting static electricity experiment

"Wow! The paper scraps jumped up by themselves!" The classroom burst into exclamations. Watching this magical scene, my heart was still pounding. This "static electricity by friction" experiment was so interesting!

The materials for the experiment were very simple: a plastic ruler, a plastic bag, and a few thin pieces of paper. I couldn't wait to take out the scissors and cut the paper into tiny scraps, scattering them on the table like snowflakes. Then, I picked up the plastic bag and rubbed it against the ruler as fast as I could, once, twice, three times... The ruler gradually became "charged"! I held my breath and carefully brought the ruler close to the paper scraps.

In an instant, the paper scraps seemed to be enchanted, like a group of mischievous little elves, scrambling to "jump" onto the ruler. Some even did a little spin in the air before obediently sticking to it. I stared wide-eyed, not wanting to miss this wonderful moment. The ruler was like a magnet, and the paper scraps were like tiny iron filings, firmly adhering to it and refusing to come off no matter how hard I shook it!

The teacher explained that this was because when the plastic bag rubbed against the ruler, static electricity was generated. Static electricity is like an invisible little hand that can "grab" light objects. No wonder the paper scraps were so obedient; they were actually enchanted by static electricity!

Although this experiment was simple, it really broadened my horizons. Such a small act of friction could create such a magical phenomenon! I love science even more now. I really hope I can do more interesting experiments in the future and explore more unknown mysteries!
