experiment

Sunday, April 1, 2006 Weather: Sunny

Today, I did an interesting experiment called "Water that can't be poured out." I first found a newspaper and a teacup, covered it, and then poured it down. As a result, the water came out. I tried again and again. The result was a failure. I wondered why the newspaper could not seal the air. This little question made me ponder for a long time. I thought about deciding to make this experiment a success. Later, I looked at the book and said, "This is because of the pressure of the atmospheric pressure." I did it according to the book's practice and finally succeeded! This is what I observed, and I finally know what the atmospheric pressure is like.
