Re: What can I mix with water to make it stay frozen longer?
Can't change the laws of physics.<br /><br />The Melting point of Water is 32 degrees PERIOD!<br /><br />Melting point of Steel is Hundreds of Degrees, That's what your looking for right?.... Just because it's not melted don't mean it's cold.<br /><br />Get your ice as cold as you can, all Ice is for you is a "Battery" of Cold. once you use up your cold, it's gone till you freeze it again.<br /><br />Once your ice melts, you now have 33 degree water, that is still good.<br /><br />Some chemicals may be able to raise the melting point, but the TEMPERATURE is still the same.<br /><br />Option 1: More Ice, get it colder to last a lil longer<br /><br />Option 2: DRY Ice, It's F'n Cold, a LOT F'n Colder than your going to get your ice<br /><br />Option 3: Get one of those 5 day coolers, REALLY thick walls, we got one for a wedding present,took it on our honey moon. I put one bag of ice in it when we left, and when I got home a week later, half was melted. Cooler was in our 70 degree room and opened maybe twice a day.
