Ball Blower Toy - Forces and Bernoulli Principle

This fun little toy consists of a foam base, plastic flexi straw and a lightweight polystyrene ball. Children can first experiment by sucking on the straw and picking up the ball with the end of the straw using suction. They then insert the straw into the base, and bend it up at 90 degrees. By blowing into the straw, they can cause the ball to levitate. The ball can even be made to float at different angles, demonstrating the Bernoulii's Principle
