"Hi my name's Addison from Captain Bill's, and I'm going to teach you how to float serve a volleyball. Float serving is probably the most effective serve there is in volleyball. When you float serve the ball actually does not move, or it's not supposed to move. Which is very hard for defenders to pass, because the ball can move, come right to them one time, and then later it can kind of move away from them, depending on the wind. Or even if it's indoor it can just drop automatically. So the float serve is very effective in both indoor and outdoor volleyball. Mainly outdoor because you have the wind to use to your advantage, which can help to move the volleyball. In float serving you want to take your hand, and you want instead of putting some top spin on the ball and using your wrist. You don't use your wrist at all you keep your hand flat the whole time. And instead of following through like you would a regular float serve, you almost in a way stop your follow through so that you can follow through to where you are serving the ball. And you want your hand flat at all times, which makes the ball stay still and float towards your opponent. And that's how to float serve a volleyball."
