For many years the favorite thing for our family was camping. And sometimes we didn't have much money for camping equipment and gear and had to find ways to make our own stuff. We did a lot of our cooking on campfires and camp stoves, and carried most of our food in coolers. There was always a problem with eggs, as the cartons would get wet and smoosh in the cooler. Tupperware came out with a little plastic jar type thing that you could use to put eggs in, and then pour them into the pan and they would come out individually. It was great. Somehow I lost the tupperware one, and really missed it. One day as I was trashing some stuff, I took a second look at the container that the powdered coffee creamer came in. I cleaned it out good, and put a few eggs in and voila! it worked just like the expensive tupperware one. I also discovered that if you put a whole lot of eggs in one, filling it pretty full you could pack it tightly into your cooler between other stuff so that it couldn't jiggle around much, you could carry lots of eggs without scrunching them in the carton. And it took up less space, and could be used for the whole time you were camping. To scramble your eggs, you could just add your ingredients and shake it up and pour right into the pan. And, then the next container was put to use for mixing and pouring pancake batter, etc. I'm sure that you could think of lots of other ways to use these.
