Here's a cool science trick for you to try: tie water in knots:
Bend Water with Static
- 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.
- Fill the container with water. You will have three streams of water pouring from the holes.
- Pinch the streams of water together. They will stick or appear to be tied together!
- 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.
