Answer:
1. When the hand was removed from the cardboard, the water remained inside the glass, trapped by the cardboard and air pressure.
2. The reason the water stayed inside the glass is because of the air pressure on the top of the cardboard. The pressure of the air inside the glass was equal to or greater than the atmospheric pressure outside the glass, creating a seal that kept the water inside.
3. In this activity, you were able to counteract gravity to some extent. The pressure of the air inside the glass, created by the difference in atmospheric pressure, was able to counteract the pull of gravity and keep the water trapped inside the glass. The air pressure created a seal that prevented the water from spilling out when the glass was turned upside down.
