Cooler Shock vs. Regular Water

Ice starts out at freezer temperature and will warm fairly quickly to its melting point (32 degrees F). Once at melting point, the ice will stay at the same temperature during the whole process of melting. After fully melting, the liquid starts to warm normally again.

Cooler Shock ice packs also start out at freezer temperature, and will warm pretty quickly, but it's melting point is at a much lower temperature — 18 degrees F. During the whole process of melting, Cooler Shock stays at this lower temperature.

When the gel liquid inside Cooler Shock packs warms up, it's starting from that colder melting point — enabling Cooler Shock packs to stays much cooler, much longer compared with the same amount of regular ice.
