Whenever I go camping, a Frisbee is a must. My brother and I can spend a significant amount of time throwing one around (and a significant amount of time running after it when one of us makes a bad throw). The last time we went camping, my brother tried to throw the Frisbee without spin. When he did this, it fell to the ground almost immediately. Why? I thought. Well, spinning the Frisbee provides angular momentum. Angular momentum is what keeps it stable. The more spin you put on a Frisbee, the more stable it is. You may have noticed that if you put a very little amount of spin on a Frisbee, it wobbles and does not go as far. To get a Frisbee to go farther on a more accurate path, put as much spin on it as possible.
