Bug Spray

Tuesday, October 21st, 2008
In Room 5 we made a spray. We got a cup of cold water and two straws. When we put one straw into the water the water comes up part way in the straw.
If we take the other straw and blow across the top of the straw in the water, the air in the straw in the cup gets pushed out, followed by the water which squirts out after it.
All sprays work in the same way.
