Scientwists - A Magical Way to Discover the World of Science

Materials:
·        paper towel
·        large/deep bowl
·        small juice glass – holds approximately 8 oz
·        water

Experiment:

1.      Fill the large bowl with water. Leave about 2”-3” space from the top of the bowl.

2.      Feel the dry sheet of paper towel.

3.      Stuff the paper towel into the bottom of the juice glass.

4.      Turn the glass upside down and slowly submerge it into the large bowl of water – make sure you don’t accidentally tilt the glass.

5.      Keep the submerged glass on the bottom of the large bowl and ask kids if they think the paper towel will be wet or dry.

6.      Remove the glass – lifting it straight up – and remove the paper towel. It’s dry!

7.      Place the paper towel back into the glass and submerge the glass into the bowl again this time tilting the glass to the side to allow the trapped air to escape – you will see bubbles.

8.      Remove the glass from the bowl and remove the paper towel. It’s wet!

What happens:

The first time you submerge the glass the paper towel is dry – the second time the paper towel will be wet

Why:

Air/gas takes up space and when you submerge the glass upside down the air pushes the water out of the way and the air pocket in the glass keeps the paper towel dry. The second time you allowed the air to escape so that the air pocket no longer exists and the water is able to fill up the glass and wet the paper towel.
