Hands up who hates buying batteries. (I had both hands up in the air by the way, briefly, but had to put them down to continue writing this article). Anyway, batteries are the bane of my life. It seems almost every toy we have for our children or gadget for ourselves require batteries. And they need them in all shapes and sizes. The worst offenders are those button-cell batteries. Small and costly...until I saw the coolest video.
