To build an accelerometer you will need, a transparent plastic tube which has a rubber stopper at both ends, a spring, a paper clip, a rubber band and some tape. You can find more information at library.thinkquest.org
An accelerometer, which measures force upon a mass, can be made at home with some fairly simple items. You need a jelly jar with a lid, a cork and a string! Secure the sting and the cork to the bottom of the lid, turn upside down and string will move in the direction of the mass.
The easiest way to build an accelerometer is to use a jar with a lid, cork, string, and a fishing buoy. Attach the string to the lid of jar and attach the cork to the other end of the string. Fill the jar with water, and place the lid on. Turn the jar over.
