Physics experiments

1. Thaleia
Egkomis Gymnasium

2. For our experiments we will need:
a glass, water, a piece of carton
What we do:
 We fill the glass with water and
cover it with the piece of carton.
 Carefully we turn it upside down,
holding at the beginning the carton.
 We move our hand away.
 The water is not coming out.

3. • The atmospheric pressure eliminates the hydrostatic
pressure that pushes the piece of paper.
