The air has weight—to show this reality by an experiment could seem to you essentially the most tough activity to date.
Fairly probably it would show to be the simplest one additionally, really easy that you could be not even enquire about it! As a result of, it’s such a sort of an experiment, if as soon as its primary idea enters your mind, you can see it very straightforward. In any other case, it’s possible you’ll waste your entire day ruminating over it.
First take two balloons, a string and a bamboo stick, about one metre lengthy. Tie the string precisely on the center level of the stick and grasp the stick excessive up someplace in order that it stays in a horizontal place, when hanging freely. Take two balloons, inflate them nearly equally and tie them with strings of equal size.
After you will have completed this, tie the strings oi one of many balloons to at least one finish of the stick and make a free knot within the string of the opposite balloon, in order that, by adjusting the knot on the stick, you’ll be able to carry the stick again to the horizontal place.
The horizontal place of the stick reveals that each the balloons have equal weight. Now take a pin and prick one of many balloons. The balloon will burst with a bang and the air in it’ll escape, inflicting the keep on with tilt to at least one aspect. Thus, this proves that air has weight. Because the air goes out of the balloon, that finish of the stick having the inflated balloon tilts, as its weight is no longer countered by the burst balloon. Nothing has modified besides that the air of one of many balloons has gone out and so it’s not contributing to holding the stick balanced in a horizontal place.
