The Speed of Light (English)
Hold a ruler or speed of light indicator, test your reaction times by working in pairs with one student holding the ruler at the zero mark between the thumb and forefinger. The first student drops the ruler and the second tries to catch it. Repeat as many times as you can to see if your reaction times improve. See if your performance changes after physical exercise or after squeezing a stress ball.
