Hanging Water

Hanging Water

·    Fill a glass of water up, and hold a piece of construction   

      paper over it tightly.

·    Tip the glass over while still holding the construction 

      paper to it.

·    After a few seconds remove your hand, the paper should stay     

      there for at least thirty seconds.

·    Take the observations (the water does not pour out)

• Air exerts pressure on the cardboard.
