A frisbee is a flying disc looking like a plastic saucer, made for throwing under different angles. A popular version of the origin of frisbee says that it was invented by a couple of students from the Yale university that were throwing metal cooking utensils for fun.
Now it is a great plastic toy to have fun with. There are two ways of throwing a frisbee: forehand and backhand. In the prior case it is thrown with your arm stretched, and in the latter with your hand, which backside is turned towards the target. Knowing both techniques will result in an accurate pass.
