We use lots of sprays in our lives. Today we made our own sprays. We got a cup of water and put a straw into it. The straw was cut so it hardly stuck out of the cup at all. We know that there is water and air in the straw. Next we were given a piece of straw each. We used this to blow the air from the top of the straw.
This causes the water in the straw to rise to the top, and as it reaches the top it is blown into small droplets which make a fine spray. 
We all tried and tried till we each could make a spray. Now we can make them easily at home.
