Does anyone know if this salt can keep ice frozen? I wanted to take some frozen meals with me and thought about putting rock salt in a cooler with ice.

I just saw that grocery stores sell dry ice. I will buy this instead of trying to make my own version.0

Dry ice is easier if you are sure no one is going to touch it bare handed. However, for future reference any salt added to a cooler of ice will cause the ice to stay frozen longer. Make sure you use a good quality freezer bag to keep whatever you are carrying in the cooler dry.0

It seems counter-intuitive, but it does slow the ice from melting in a cooler. Works great for beer!!0
