Water and air

Today the chickadees and I made a science experiment.

This experiment can be found in

 Want to keep water from falling out of an upturned glass?



This is what you will need:

 thin flat card, a glass, water and sink or large bowl

Hold the glass over a sink or large bowl.

Carefully pour some water into the glass.
At first we filled it to the rim but it didn't work.
Then we tried it again with about 1/4 inch less of water.

 Place the card on the glass,

 making sure the card touches the rim all the way around.

Still holding the card to the glass,
turn the glass upside down.

 Let go of the card.

And look!
It's magic!
The water stays in the glass!


Try it with your children!
Or try it by yourself!
I thought it was pretty neat :)
