No need for batteries with this calculator. The Water Powered Calculator runs by the power of hydro. To power the device you just pour water into the rear power panel, place the stopper, and the electrolytes in the water generate enough power to keep this little guy chugging along, squaring your roots.
The device is said to be perfectly safe, and we guess we see how it could be, but mixing water with its large LCD screen can’t make the calculator a gadget that lasts too long. Water is bound to leak into the screen, we would think. But definitely a cool idea fo’ sho’. Get yours for $8.99, plus the cost of utilities. — Andrew Dobrow
