TO PROVE THAT AIR HAS WEIGHT!

Let us look at an experiment which would prove that air actually has weight!

Materials Required

• Two balloons
• A ruler
• Tape
• String

Instructions

1. Inflate one balloon and tape it to one end of the ruler. Don't inflate the other one and tape it to the other end.
2. Tie a string at the middle of the ruler and tape the other and to the wall.

Observe how the ruler end with the inflated balloon attached, dips

Observation: We see that the end of the ruler, which has the inflated balloon attached dips. This suggests that there is more weight on that end than the other. But the only difference between the two balloons is that one is inflate, that is, it contains air. If we burst the balloon using a pin, we would see that neither of the ends are dipping. Thus we conclude, air has weight.
