In this activity, you’ll open your non-dominant hand (the hand that you don’t use for writing) and then squeeze it into a tight fist as quickly as you can for 100 seconds and write down the number of squeezes every 10 seconds. If you have access to a ball, you can squeeze the ball with your non-dominant hand instead. How do you think the number of squeezes you can perform will change over the course of the experiment? How many squeezes do you think you can perform during the last 10 seconds of the experiment?
