Science Projects And Inventions

YOU NEED:

• A clear plastic jar

• A marble

Take a transparent plastic container and put a marble inside it. Now move the container in a circular motion,

duly maintaining contact with the table top. The marble moves up the sides of the container and revolves

around the walls.

HOW DOES IT WORK?

This is caused by the centrifugal force which moves outwards and upwards those objects that are travelling

at high speeds. While travelling in your car you feel a similar pull, outwards, while taking a turn around a

corner at speed. This is how stuntmen ride the motorcycle inside a round cage in the circus.
