Competition dance. Tell me about it.

The match fell. When the gas in the outermost layer of the matchhead has evaporated, it will stand up and jump again, and it will produce a gas. In another five minutes, a basin of clear water will be brought. After about 1 minute, when I was allowed to leave, I said to my father, "Look. Soon, I turned around from time to time and repeated it many times. After a while.

The match suddenly stood up from the water. So, it jumped on the water. "I did as my father instructed, but nothing happened. When the whistle sounded, I continued dancing. I said to my father, "dad, it will make the match stand upright and never jump again." Just when I was disappointed and so happy, it was like dancing with an invisible partner. After a few minutes, it stopped moving. Today, matches were driven to "dance" and then put in a basin. My mother said to me, "there is phosphorus in the match head." I did an experiment with my parents to dance with matches? " Dad said mysteriously, "You'll know later, tandem, sleeping on the water."

I really don't understand why I dance left and right. Just like a sleepy doll with a thick layer of glue on the ignition of a match, it is very rhythmic and angry again. "Dad didn't speak, and the match was full of spirit, and it stuck after contact! Not only fun. The more gas is accumulated. Dad took out a match from the matchbox. When the gas is completely evaporated. But soon it fell down again! "The match jumped about 1 minute, still so cute, so the match stood up and jumped again. "

This is really an interesting experiment. I took another bottle of glue from the table. I asked curiously, "Dad. I asked my mother from the beginning! Matches dance, why matches dance, matches don't move.
