Our daily life is full of scientific knowledge which sometimes we notice little.During hot summer time,I was told by my father that I could not fill the tire with too much air when my bicycle tire went flat,which had really bothered me to get the reason.
With the confusion,I planned to make an experiment with my bicycle tire.As a start,I filled the tire with full air,and then began to ride it .Just covering no more than one mile on the hot ground made by the sunshine,I heard some noises from below,only seeing my tires broken after them blowing up.
At last,I came to a conculsion that any object size expends when heated.
