Kendamas 

You still don’t know what a Kendama is? Yes, I know what you are thinking, but stay calm we also have other hobbies other than YoYos and Kendama is one of those. Kendama is a Japanese toy made of wood that has the following two parts: the Ken (the hammer) and the Tama (the ball). Both parts are connected by a string and the ball has a hole on the bottom so you can put it in the Ken. Kendama is an addictive game that will make you develop new skills before you know it.
