This document describes an experiment to demonstrate centrifugal force using common household items. A plastic water bottle is cut open and holes are drilled into it. String is tied through the holes and to a pencil to create a spinning device. Wet cloth pieces placed inside the bottle are spun and centrifugal force throws water from the cloth, drying them without the use of a traditional clothes drier. Centrifugal force is the principle behind how clothes dryers work.

070 DEMONSTRATION OF CENTRIFUGAL FORCE MATERIALS REQUIRED : Plastic mineral water bottle Pieces of cloth A pencil A string
A plastic bottle is taken and is cut at the top portion.
Many holes are put all over the bottle and a string is tied at both the ends of the bottle.
A pencil is wound tightly around the string and pieces of wet clothes are put into the bottle. Pencil
Loosen the string now such that it rotates faster. Clothes get dried due to the centrifugal force which is the principle of drier. Pencil Pencil
