- Get a jar of jelly beans or else something small in a large bowl or bottle
- Gather a large group of different kinds of people at varying degrees of math skills

- Take the average of all the guesses, and, invariably, the average is closer to the correct amount than any one person
Try it out yourself and you will see that this is true. I guess it just proves my slogan for my college experience: cooperate and graduate.
