Bending a stream of water with a comb


Aim:

To understand how static electricity works with a simple experiment.

Materials required

  • A water faucet.
  • A plastic comb.


Procedure:


  • Run the comb through your hair thoroughly
  • Open the tap and let the water flow with minimal force. Do not open the tap too much as the water stream needs to be thin.
  • Bring the comb close to the water and hold it around 1-2 inches away from the water and 3-4 inches below the tap.
  • Observe the stream of water bending towards the comb

Scientific explanation:

When two objects are rubbed against each other, electrical charge is accumulated. Before rubbing, the objects would have been electrically neutral, that is, they would have had equal number of positive and negative charges. However when they are rubbed together, depending on the nature of the objects, charges of one kind will get transferred to one of the objects so that one object will have a net positive charge and the other will have a negative charge. When you rub the comb through your hair, the comb accumulates one kind of charge. This charge attracts the stream of water and makes it bend towards the comb.

Fire Water Balloon

Materials The materials required for this science fair project: - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure 1. For this experiment, the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount of water in the balloon. 2. Inflate the yellow colored balloon and tie it up. 3. Pour half a cup of water into the blue colored balloon before inflating it to the same size as the yellow color balloon and tie it up. 4. Light up the candle. Be careful when using match sticks to avoid causing fires, or burning yourself. 5. Hold the yellow colored balloon on top of the lit candle. Observe and record what happens. 6. Hold the blue colored balloon on top of
