Ice is great for many scientific experiments and research. It's cheap, easy to make, and always fun to experiment with.
Today we are going to try a great sA scientific trick in which a wire cuts through an ice cube. Normally, ice needs to be heated to melt, but it can also be melted by applying pressure. To do this, weights are attached to a thin wire placed over the ice cube.
You will need:
Fine wire, we use fishing rod wire.
Ice cubes
1 or 2 weights
Container for storing ice cubes
How to move a cable through ice
Place an ice cube on a bowl. The ice cube should be stable.
Cut the wire to a length that will fit over the ice cube but will not reach the surface when the weights are added.
Place a small weight on each end of the wire.
Place the wire over the ice bucket so that the weights hang evenly over each side.
How does it work? Wire cut through ice?
When water freezes, it expands as the water molecules arrange themselves in an orderly arrangement that takes up more space than when the molecules are free.
The wire exerts pressure on the ice below, which melts it slightly. As the wire moves down, the water on top refreezes. This continues as the wire moves through the ice.
