Disk tendencies

[Tom Line]

The frisbees are, in essences, a gyroscope. Their spin resists flipping. You can test this by bouncing them off the wall. Most will land upright. However, I would always design for the worst case.

Thrown like a coin, they should tend to land upside down - the solid top and open bottom moves the center of gravity to the top of the frisbee, and without the spin they have nothing to counter balance it.

However, I expect with the coriolis effect of the earth, teams in Australia may find this is all backwards from what they expect. That will make it a very difficult challenge for them.......
