Answers
Answer:
The reason this experiment works is because of air pressure! Air pressure is the weight of a column of air pushing down on an area. While we cannot feel it, the air is heavy! The weight of the air pushing down on all objects on Earth is the same as the combined weight of three cars! The reason we don’t feel this extreme weight is that the molecules in air push evenly in all directions– up, down, sideways, diagonally. In this experiment, the air pushing up from underneath the paper is strong enough to overcome the weight of the water pushing down on the paper. Because of the air pressure pushing up on the card, the card will stay on the glass and the water will not spill out
