Float a ball (twin pack)
Float a Ball toy is a toy that relies on Bernoulli's principle so when you blow through the pipe the ball floats in the air. This toy is made of plastic so it is easier to clean if used for multiple children. This makes it an ideal tool for strengthening lungs and facial muscles for speech. As the ball floats up and down as you blow it also works as an eye strengthening exercise to improve tracking as you watch the ball move around.
