Obedient little paper man

On the morning of Friday, I read a book with a small experiment on it; a small paper person obedient. This interesting name attracted me. I found a newspaper according to the book, and then asked my father to come with me.

I first found a thick piece of paper and cut some crooked little paper people. Dad took the newspaper and baked it around the stove and stuck it on the door. "Dan Dan, take a pin." "Come." Dad put a pin on each of the paper people's feet and arranged them neatly in a metal plate.

Dad "uncovered" the newspaper on the door. Both hands were flat and held close to the metal plate. Interesting things happened. The little paper people seemed to stand up when they heard the password! When Dad moved the newspaper to a farther place, the little paper people lie down again. Dad didn't let them rest more, and when they got closer, they moved away, and the little paper people stood up for a while and lay down.

I asked my father why he should have a pin on the little paper man's foot. Dad said, "If I don't take the pin to keep them, they will jump up and stick to the newspaper. I don't believe you." Dad put the little paper man The pins on the feet were pulled out, and the newspapers were close to them. Sure enough, the little paper people, like the iron filings, met the magnets and posted them on the newspaper. It turned out that this is the reason for frictional electrification.

This successful small experiment has increased my interest in learning scientific knowledge. I know that there are still many scientific secrets waiting for us to explain it!
