A simple experiment to illustrate the principles of centrifugal forces.

1. 070 DEMONSTRATION OF CENTRIFUGAL FORCE
MATERIALS REQUIRED :
Plastic mineral water bottle
Pieces of cloth
A pencil
A string

2. A plastic bottle is taken and is cut at the top portion.

3. Many holes are put
all over the bottle
and a string is tied
at both the ends
of the bottle.

4. A pencil is wound
tightly around the string
and pieces of wet
clothes are put
into the bottle.

5. Loosen the string
now such that it
rotates faster.
Clothes get dried
due to the
centrifugal force
which is the
principle of drier.
