Trap+Water+with+Holes!

You can keep water inside a glass by covering the top of the glass with a piece of cardboard full of holes!

To trap water with holes you need:
 * a glass
 * water
 * thin cardboard
 * thumbtack or small sharp nail

Directions:
 * 1) Poke lots of holes into the bardboard with a thumbtack or nail.
 * 2) Fill the glass with water untill it is over-flowing.
 * 3) Press the cardboard over the top of the glass until water squishes through the holes.
 * 4) While still pressing the cardboard over the top of the glass, turn the glass upside down.
 * 5) Take away your hand. The carboard sticks to the mouth of the glass and the water doesn't drip through the holes.
