Today,with the help of our physics teacher,we carried out an interesting experiment in class.
Before we started,we prepared a candle,a basin,a glass and some water.By the way,the glass was a little higher than the candle.First,the candle was kept standing at the bottom of the basin and some water was poured into the basin.Then we lit the candle,covering it with the glass that was full of air.What we had to do was to wait until the candle went out.
To our astonishment,we saw that the water level in the glass was higher than that in the basin.What an interesting experiment lesson we had!
