    • The cloth rubbing wool is used to perform the static electricity experiment.
    • A cloth rubbing wool is used for rubbing against different materials, such as glass, plastic, balloon, wax.
    • Wool cloth is used to demonstrate experiments for balloon and wool cloth.
    • When rubbing a balloon with a wool cloth, the balloon captures electrons from the wool, leaving the balloon with a negative charge and the wool with a positive charge.
    • If both balloons are rubbed with wool, they will both have same charge (negative) and therefore will repel each other. When you spray water near the balloons.
    • The water droplets carry the charges away from the balloons, leaving them uncharged. As the balloons become neutral, they will fall back together.

    Description:

    • Aneroid Barometer is a scientific instrument that is used to measure atmospheric pressure (with the change of the distance below and above sea level). It is also names as barometric pressure.
    • Barometer is kept at the same level and can measures easily the pressure changes by weather and different causes of weathers.
    • Measuring air pressure using these instruments the usage of liquid is not required.
    • The instrument is designed with a small metal box named as Aneroid cell (Capsule) it is designed from alloy of Beryllium and Copper.
    • This expansion and contraction procedure drives mechanical levers i.e. the tiny movements of this capsule are amplified and are displayed on the screen of measuring barometer.
    • It is also used in different meteorology, in barographs and to create pressure in radiosonde.
    • Aneroid barometer is highly a sensitive instrument and can be used to record small changes in pressure.
