Water, water, every where, Nor any drop to drink
That often-misquoted phrase reminds us that not all water is potable - normally due to its high sodium content, incompatible pH level, and native plant and animal life. There are a myriad of treatment options available to you, but regardless of which one you chose, one thing is certain: you'll need math to figure it all out. And what better to help you with your calculations than a calculator. While you're at it, use water to power the calculator!
That's right - to get this calculator juiced up, just add water (regular tap or filtered water, only). A cap full of water in the H2O battery can power the calculator for up to 3 months. And this calculator isn't a wimpy, dinky thing; you get a full-function calculator with large keys and a large 12-digit display. A calculator is basic office gear, everyone needs one. Geek your calculator up a notch - make it water powered!
