Your Child Can Do Magic With Water.

GRAVITY FREE WATER OR MAGIC TRICK

What goes up must come down?  Is that true?  Have your child find out by using a glass filled with water and turned upside down.  All he or she will need is a piece of cardboard and a little air pressure.

What your child will need:

• A glass of water filled to the tippy top

• A piece of cardboard

Instructions:

• Make sure the glass is filled to overflowing.
• Slide the cardboard over the mouth of the glass and make sure no bubbles or air enters the glass as you hold the cardboard over the top of the glass.
• Turn the glass over and upside down.It is best to do this over a sink or outside.
• Take away your hand that is holding the cardboard.
• Guess what?The water did not fall out and the cardboard did not fall.

What happened?

Defying gravity, the water stays in place.  Why?  Since there is no air inside the glass, the outside air pressure is greater than the water pressure inside the glass.  The air pressure actually holds the cardboard in place and the water inside the glass.
