Introduction
Think fast! Have you ever noticed that when someone unexpectedly tosses a softball at you, you need a little time before you can move to catch it (or duck)? That's because when your eyes see an incoming signal such as a softball, your brain needs to first process what's happening—and then you can take action. In this activity, you can measure just how long it takes for you to react, and compare reaction times with your friends and family.
