• An empty plastic bottle
• A sharp pencil
Gravity disappears inside a freely falling container. This is one trick that should preferably be performed
outdoors.
Make two holes on opposite sides of a plastic bottle near the bottom with a sharp pencil. Fill the bottle with
water having put your thumb and forefinger over the holes.
Should you remove your thumb and forefinger, gravity will force the water to come out.
Interestingly, if you hold the bottle at a height and let it fall, the water will remain in the bottle.
It is much like a spacecraft as it orbits Earth.
HOW DOES IT WORK?
In a gravitational field, everything falls at the same speed no matter what its weight is or what it is made of.
In this particular experiment, the water does not come out because both the water
