Answer 2

Answer:

Crush a Plastic Bottle Science Experiment

This super simple experiment seems almost magical, but don’t worry, it doesn’t require a magician! It can only be explained through a better understanding of air pressure.

Even though most of the time you can’t see or feel it, the air around us is pushing against every surface and by making a change in air pressure, we can crush a plastic bottle without ever touching it.
