Zap!

You are a frog using high tech visual and audio detecting equipment to track incoming flies. Test your reaction time by hitting the big red button when you see or hear a tasty insect!

 

Reaction Ruler

The Reaction Ruler is a bookmark, a handy centimeter ruler, and a tool that measures your reaction time. Just ask a friend to hold the ruler at the yellow diamond, so it hangs straight down. Put your thumb and forefinger around the ruler right at the yellow star, so that you are ALMOST pinching the ruler (but not quite). Your friend should let go of the ruler, letting it fall. And you try to pinch your fingers closed, catching it as quickly as you can. Then read the red number nearest where you catch it; that tells you how long it took you to react. Try practicing to see if you can improve your time!
