How do you do the water in the cup trick?

An Easy Science-Based Illusion Essentially, you pour some water into a cup and wait a few moments. Then you turn the cup over, but no water pours out—the water has apparently vanished. There’s nothing special about the water or the cup, but there is something inside the cup that your audience doesn’t know about.

Can water stay in a cup upside down?

Your body is used to feeling this kind of air pressure, so you don’t notice it. When you first turn the cup upside down, the pressure of the air inside the cup and the air pressure outside the cup are equal. All of this is possible because the water creates an airtight seal between the rim of the cup and the card.

How can you make water float?

Why does water not fall out of a glass?

Air pressure is the weight of a column of air pushing down on an area. While we cannot feel it, the air is heavy! Because of the air pressure pushing up on the card, the card will stay on the glass and the water will not spill out.

What happens to water when it is heated?
