Science Week

Science Week

As part of science week, we undertook an investigation. We wanted to see what happens when we placed a straw in a glass of water, and then blew through another straw on top of the one in the water.

The fast flowing stream of air when we blew through the straw made a decrease in the air pressure. The water rose to the top of the glass and sprayed out. This is similar to the way cleaning sprays and perfume bottles work.
