We all remember how our parents used to get by with battery-powered calculators – you know, the ones that could only display eight digits at a time, and would get passed around the office every now and then. Today, everyone who has a cellphone (which basically means EVERYONE) has a powerful calculator in their hands, and battery-powered calculators are now a thing of the past. Or are they?
Apparently they’re making a comeback as a funky cool gadget, a water-powered calculator at that. This device uses water to help the battery power the unit – a little water is enough to power the little thing for about a month. It comes in a hip, trendy blue-and-silver design and will definitely be loved by people who STILL use handheld calculators (surprisingly, there are a lot of them still hanging around).
The water-powered calculator costs about $20, which makes it a great gift item – especially since all it takes to power the thing is water. It may not be a scientific calculator, but they’re probably working on one right now.
