How long do you need to freeze slushy magic cubes?

The amount of time needed to freeze slushy magic cubes depends on the size and shape of the cubes, as well as the temperature of the freezer. Smaller cubes will freeze more quickly than larger cubes, and cubes with a simple shape will freeze more quickly than cubes with a complex shape. In general, it will take approximately 4-6 hours to freeze slushy magic cubes in a standard household freezer. However, it is always best to check the cubes after a few hours to ensure that they are fully frozen.
