Herb Gottlieb adds:

5. Shotgun targets (instead of tossing up clay pidgeons)
6. Outdoor game of throw and catch
7. Carnival game. Toss them into a standard
        5-1/2 inch diameter pot that is at least
        5 feet away from you. (Try it! It's real fun.)
8. Template for drawing circles or Venn diagrams on a chalkboard.
9. Dropping target for "monkey and hunter" demos.
10 Electrostatic charge holders for electrostatic demos.
