¼ö¾Æ,Çö¿õ Do you know what¡¯s inside balloon?
Yes Air. The balloon is filled with air. But is it heavy?
Can you feel its weight? Can you measure the weight of air? Well. I can¡¯t . it is too difficult.~~but today, I can show you some exciting experiment.
Look. the left balloon is level with the right balloon.
Now. Let¡¯s open the opening of the left balloon to make it loose its air. ½¬~~ÀÍ! what happened? it lost its balance. Which one is heavier? Why???
We can guess that the left balloon is lighter than the right balloon.
It¡¯s because the right balloon has air in it.
It means that air has weight. That¡¯s why it lost its balance.
