Name: Catch a Dollar

Comments: Have a student try to catch a dollar bill with their fingers starting at the midpoint when you drop it. It takes about 0.12 seconds for the dollar bill to drop out of the student's grasp - faster than a typical reaction time. If you're feeling really lucky, tell the student that he or she can keep the dollar bill if caught.
