This is a hands-on demonstration that involves students working in pairs doing an unfamiliar task with both their dominant and non-dominant hands.

Students are placed in pairs. Each pair is given one plastic bead box that has two compartments in which there are 10 wooden beads. They are also given four chopsticks. Starting with all of the beads in one side of the box, the student uses the chopsticks to move all of the beads to the other compartment. The partner keeps and records the trial times. They do this first with their dominant hand and then with their non-dominant hand.

- It yields data that shows that hand dominance is often not so dominant.
- It allows students to run an experiment by themselves.
- It gives them practice in data collection and recording.
- It teaches them a skill that will prevent them from being embarrassed when they go to an authentic Asian restaurant.
- It can allow you to compare the scores of the boys and the girls.
- It allows you to compare the scores of the lefties and the righties.
- You may use the numerical data to do simple statistical manipulations, i.e., mean, mode and median.
