Understanding Air Pressure Weather Science Experiment
In this fun and easy weather science experiment for kids, we’re going to investigate and understand air pressure.
- Fill the glass with water.
- Put the straw in the water and suck some water about halfway up the straw.
- Put your finger over the top of the straw.
- Pull the straw out of the water.

How it Works:
The water stays in the straw because the only place air pressure can get into the straw is from the bottom. This holds the water in the straw.
Make This A Science Project:
Try a larger diameter straw like a milkshake straw. Try adding a drop of dish soap to the water. Try tilting the straw.
