Static Electricity Experiment

Charging up a Bulb

Materials you will need: • A Dark Room • Fluorescent Light Bulb • A Comb/Woollen Scarf

Steps:

1.  Go into a dark room with the light bulb and the comb (woollen scarf).
2.  Run the comb through your hair around 20 times.  You could rub the comb over a woollen scarf for the same effects.
3.  Place the comb on the metal end of the light bulb and watch as the filament in the bulb lights up.

The friction between your hair and the comb causes electrons to travel from your hair to the comb.  This causes your body to become positively charged and the comb becomes negatively charged.  With the comb being charged, it discharges into the light bulb causing the bulb to emit the small pulses of light.
