How to Weigh Air

How to Weigh Air

 Experiments 2

In this experiment I'm going to be teaching how we can weigh are. There has been lots of questions concerning the fact that air has weight, we are going to clear all those confusions now, because we will be weighing air in this experiment.

Please Subscribe to this website for experiments directly to your inbox.

For this experiment, you are going to need 

  • Two plastic sticks, one 15cm and one 30cm
  • Balloons of equal sizes, eqch slightly inflated.
  • Two cans of drinks
  • Sticky Tape
  • Pencil
What to do

  1. Mark the centre of the 30cm plastic stick with the pencil
  2. Fix one balloon at each end of the stick with sticky tape
  3. Tape either end of the 15cm plastic stick to a can. Place the centre mark of the 30cm stick on top.
Observation Noted

The stick with the two balloons stay horizontal.

Because: the balloons are of equal weight.

  1. Remove one balloon and inflate it fully. Reattach it to the 30cm plastic stick, Making sure it is as it was before.
What Happens: The fully inflated balloon weighs down the long plastic stick at one end.

Because: The air inside the fully inflated balloon makes it heavier than the other one.

This means air has weight
