Cool Science Trick - Tie Water in Knots

By November 3, 2013

Follow me on:

Here's a cool science trick for you to try: tie water in knots:
  1. Take an empty carton or jug, such as a milk or orange juice carton or jug. Poke three holes near each other near the bottom of the container.

  2. Fill the container with water. You will have three streams of water pouring from the holes.

  3. Pinch the streams of water together. They will stick or appear to be tied together!

  4. This is caused by the high surface tension of water. Water molecules are cohesive or stick together. The water molecules are in a state of lower energy when they are in contact with each other, so once joined, the water streams tend to run together rather than separate again.
