Pulse Indicator Science Fair Project

The human heartbeat creates the pulse in the arterial system of the body and this can be detected using the Pulse Indicator. This simple instrument will enable you to detect your own heart-beat pulse easily. To make the Pulse Indicator, insert a drawing-pin/thumb-tack into the base of a match-stick and balance it on your wrist at the spot where you can feel the pulse with your thumb. Place your arm at rest on a table. The tip of the match will vibrate slightly, with each pulsation of the heart-beat which indicates the pulse.
