How to Melt Ice Without Using Heat

Locate an icy area on your sidewalk or driveway. Take calcium chloride salt (rock salt like you buy in winter for the roads and sidewalks) and spread it over the ice. Try to estimate equal parts ice and salt.

Wait for the ice to melt. The calcium chloride will add ions to the ice mixture, which will speed up the ions present in the ice and lower its freezing point. The more rock salt you add, the lower the temperature it will take to freeze the ice again.

Speed up the melting process by pressing on the ice and salt mixture. According to the University of Illinois Department of Physics, this type of pressure will melt the ice in a similar way to that of ice skates creating a slight depression in the ice beneath your feet.
