Science Project “How to Merge Streams of Water” Complete School Projects on Air, Water, Weather and Temperature for Class 8, 9, 10 and 12 Students.

How to Merge Streams of Water

Materials Required:

  1. A plastic bottle
  2. A screwdriver or poker
  3. Some water

Would you like to do something that has a scientific reason and conclusion to it, but seems to be magical?

 You can make three streams of water blend like magic into a single flow and then make them go their separate ways, if you first pinch the three together and then brush a finger over them.

Use the screwdriver to make three holes side by side, near the bottom of the plastic bottle.

There should be a gap of a quarter inch between the holes. Once the bottle is filled with water, you will witness water coming out in thin streams from the three holes, you have made. Now try pinching the three streams together with your thumb and forefinger.

 The three streams will join and form a single stream.

Brush your forefinger across the holes and lo the water will sprout out separately again. Water molecules have a negative charge on one side and a positive charge on the other. The side with a negative charge attracts the side which has a positive charge and they stick together.

Once the streams of water are pinched together, the water molecules from the three separate streams come close and they stick. When the forefinger is brushed across the holes, the streams of water are interrupted momentarily and the water starts flowing in separate streams, placing the molecules too far apart to attract each other.
