Pressure Experiment - Paper Plunge
 
The Paper Plunge

Materials you will need:

Clear Glass
Big Clear Bowl of Cold Water
Scrunched/crumpled up piece of paper

How did that happen?

 
Steps

1. Fill the bowl with water.

2. Scrunch or crumple up the piece of paper.

3. Push the paper into the bottom of the glass so that it cannot fall out.

4. Turn the glass upside down and plunge it straight down into the bowl of water.

What happens to the paper?

Where is the water level in the glass?

How this works - The air inside the glass takes up space and pushes.

The paper stays dry because the water can only get into the glass by squashing the air inside it.

Air can be squashed, or compressed, a little, but then it pushes back and prevents the water from reaching the paper.
