Balloon Balance Experiment
Hypothesis: We will prove that air has weight / mass by building a balance scale and performing an air weight experiment.

Materials Required
Check out the concise list of supplies…
Two Balloons
A piece of string
Ruler / long stick (Wooden or steel)
Any sharp object like needle or pin
Scotch Tape
Materials Required
Building a Balloon Balance
Step-1: Build a balance using a ruler and strings! Take a ruler of your chosen material and give it a knot using a piece of string but precisely in the center. Make sure the string is strong enough to hold and balance the ruler scale in place.

Step-2: Now, bring the balance over your work table and attach the other free end of the string to support on the top. If you have a readymade balance available readily at home, then you can also use it.

Step-3: Then, pick the two balloons and blow them up. But you need to blow the two balloons in equal size.

Step-4: After checking, give the balloons a knot at the mouth of them using an equal length piece of string.
Step-5: It is time to fix the balloons on either side ends of the ruler, leaving 3-4 inches of space from the end of the scale. Fix the balloons to the ruler using the other free end of the string attached to the balloon.
Balloon Balance Air Weight Experiment
As we are taking equal length strings to both the balloons to secure them, we must mostly observe the balloons at the same height even after tying them to the ruler. Finally, you need to check whether the balloons are at equal height from the ruler.

Step-6: At this stage, leave the balance attached with equal-sized and inflated balloons freely. That means let the balance adjust itself, and then you check, both the balloons remain at the same height as the ruler.
It shows that air inside both the balloons has equal mass and remains at the same height when left on balance freely.
Step-7: In step-7, we are going to prove that air has mass! To prove this, pick any sharp object and poke any of the two balloons.
Immediately, you can observe the balance goes down on the side where there is an inflated balloon and the side consisting of deflated balloon goes up.
Just like a see-saw, you can observe the actions of balance when you deflate one of the balloons using a sharp object.

You can alter the experiment with varying mass of balloons to check the results.
