You need : ten minutes, box of milk duds, pair of chopsticks.

1. Find a quiet place to sit, on a tabletop or the ground. Imagine you have two sides in front of you, left and right, and an imaginary line in front of you. On one side you will place your milk duds. using your dominant hand try to pick up the duds one by one and place them to the other side of the line with your chopsticks. This may take several tries before you succeed at moving them.

2. After you master the art of transferring them from one side to the next, begin to time yourself and see if you can minimize the time it takes you to transfer the whole box of milk duds using your other hand.
