Why does water stay in a straw when you cover one end?
It’s a basic demonstration of the forces of nature. Sealing the top of a straw with your finger stops air entering and exerting a downward force on the liquid, leaving only the upwards force of air pressure from below. This upwards force is stronger than the force of gravity pulling down on the liquid.
Is there a limit to how long a straw can be?
Yes, the limit is about 30 feet, due to the weight of water. See, when you suck liquid through a straw, you’re reducing the pressure at the top of the straw, which draws the water up. The longer the straw, the higher the column of water, which means there’s more weight trying to pull it back down.
