Have you seen a tennis ball launcher? No? Well, in this kit, you will learn how to build your very own ball shooter! But instead of using a tennis ball, you will be shooting with a foam ball with extreme speed! While building the launcher, you will also learn how to connect a DC motor with hook up with wheels which creates friction on the foam to launch it forward.
