Hello,this is Li Hua.In sunday morning,Wang Lin and I made a experiment about the atmosphere peressure,and here is the course.
1.Prepare three things:a candle,a plate filled with water and a glass so we can see what happens from the outside of it .
2.Put the candle in the plate and light it.
3.After a while, put the glass in the plate,make sure the candle is in the glass and the top of the glass is surrounded by the water.
4.Wait for a second,we can see the fire goes out and the water level in the plate goes up.
So , This is the result.We can learn the atmosphere peressure is everywhere arround us,and it is bigger than we thought,is it?
