Okay, so I recently went on a field trip and forgot to put ice in the cooler. I didn’t want to buy a whole bag for my small cooler and also didn’t want botulism from the mayo on my sandwich. I had to run in the grocery store to grab a couple of snacks and thought perhaps they would have some cooler ice packs in the freezer section. (I have seen them before) Anyway, I was in no such luck today. So what did I do? I bought a bag of 97 cent frozen corn and put it in the cooler! It was cheap, worked perfectly, and our lunch was still positively frigid when we were ready to eat. It Worked for Me!
