There is a lot of debate surrounding the use of salt and ice in coolers. Some people swear by it, while others think that it's nothing more than an old wives' tale. So, what's the truth? Does salt really make ice last longer? In this blog post, we'll take a look at the science behind salt and ice and find out if it really works!
One of the most important things to consider when using salt and ice is the type of cooler you're using. If you're using a cooler with a lot of air space, like a Styrofoam cooler, then salt will not make much of a difference. This is because the ice will melt faster in the larger volume of air. However, if you're using a cooler with less air space, like a Pelican Cooler with tightly packed ice, then salt can help to make the ice last longer.
The science behind this has to do with the way that salt lowers the freezing point of water. When you add salt to ice, it causes the ice to melt. This is because the salt dissolves in the water and creates a brine solution. This brine solution has a lower freezing point than pure water, so it causes the ice to melt.
However, the ice will only melt if there is enough salt present to lower the freezing point of the water. If you don't add enough salt, then the ice will simply stay frozen. So, if you're trying to make ice last longer, it's important to use enough salt.
In conclusion, don't fill your cooler with salt. It won't necessarily extend the life of your ice. If you want your ice to keep longer, consider using Pelican Ice. We have Pelican Ice available in 2lb or 5lb versions.
