Hi Maria,

We have an answer to a similar question, about why ice melts more slowly in salt water than in fresh water .

Ice cubes, if they are much colder than the freezing point of water (for example, when you take them out of a very cold freezer), have the ability to freeze a little bit of water around them as heat is transferred from the water into the ice cube, warming it up. If two very cold ice cubes are very close together when put into water, they may freeze the water between them solid and therefore become stuck together.
