The foam whistle ball with aerodynamic tail maximizes speed and distance for long throws. Two whistles produce a fantastic whizzing sound as the ball speeds through the air, which lets your opponent know the ball is on its way. A hand grip lets you hold tight for less fumbles and longer distance. Foam whistle ball makes an amazing outside activity. Boys and girls will love its crazy sounds and long flight. Best for lawn, beach and backyard fun. It is 10 inches long. A fun way to learn to throw and catch. Great for hand/eye coordination.. Comes in two colours: Red and Black.
