Move a wire through ice – ice cutting experiment

Published: May 2, 2023 by Emma Vanstone · This post may contain affiliate links · 4 Comments

Ice is great for lots of science experiments and investigations. It’s cheap, easy to make and always fun to experiment with.

Today, we are going to try a cool science trick where a wire cuts through an ice cube. Ice usually needs to be warmed up to melt, but you can also make ice melt by adding pressure to it. We do this by adding weights to a thin wire placed over the ice cube.

You’ll need:

Thin wire, we used fishing rod wire

Ice cubes

1 or 2 weights

Container to rest the ice cubes on

How to move a wire through ice

Place an ice cube on top of a container. The ice cube should be stable.

Cut the wire to a length that will fit over the ice cube but not reach the surface when the weights are added.

Attach a small weight to each end of the wire.

Place the wire over the ice cube so the weights hang evenly over each side.

How does the wire cut through the ice?

When water freezes, it expands as the water molecules arrange themselves in an ordered arrangement which takes up more space than when the molecules are free.

The wire adds pressure to the ice under it, which melts the ice a little bit. When the wire moves down, the water on the top refreezes. This continues as the wire moves through the ice.

    That is a very very cool experiment. Ice just has so many interesting properties. I want to do this with my kids.:)
