Make Mist Cool Science Experiment
In this fun and easy cool science experiment for kids, we’re going to learn how to make mist and demonstrate Bernoulli’s Principle.
Materials:
- Straw
- Scissors
- Glass of water
Instructions:
-
Cut a horizontal slit in a straw about of third of the way from the bottom of the straw. Leave enough of the straw connected so you can bend the straw at the slit without the bottom section breaking off.
-
Put the short end of the straw in the water, keeping the slit about one quarter of an inch above the water level.
-
Blow hard through the long section of the straw.
-
A spray of mist should come out the other end of the straw.

How it Works:
Mist is nothing more than tiny little droplets of water suspended and moving in the air. Mist can cool through evaporation in a way similar to human sweat. Blowing air through the straw creates a low pressure zone that pulls up the water from the glass. When this liquid meets the blast of air, it breaks up into a fine spray. This is a great activity to demonstrate Bernoulli’s Principle.
Make This A Science Project:
Try different sized straws. Try cutting the slit at different lengths from the bottom of the straw. Spray same amounts of mist on different colors of construction paper. Place the papers in the sun and determine if one evaporates quicker than the others.
