Dry times

 

 What you need:

Newspaper

Water

Bucket or deep bowl

Plastic or glass container

 

Instructions

Fill the large bowl about two-thirds full with water. Scrunch up the newspaper and stuff it firmly into the container.

Plunge the container straight down into the water, wait about 20 seconds, then lift it straight out again without tilting or turning it.

 

Results & explanation

When you take the newspaper out, it is completely dry!

Water cannot fill the container because of the air trapped inside it. The air gets squashed a little, but the air pressure is enough to push against the water so it doesn’t get into the container or touch the paper.
