Does Food Coloring Or Salt Water Effect How Fast Ice Cubes Melt?

Ice will melt faster if it is formed of salt water. This is not because it becomes warm faster, it is because salt water doesn't need to get as hot to become a liquid. Ice made from fresh water will also melt faster if it is placed in water than left in the air because water is not a good insulator of heat.

The effects of Food Coloring depends on the chemical used to produce the coloring.
