The other day a friend of mine asked if I had ever heard of a AAAA battery. During the enormous amount of reading about flashlights I have done, I remember someone saying that a 9V battery is really 6 1.5V AAAA batteries bundled into a box. So I told him that not only had I heard of them, I knew where you could get some and explained about 9V batteries. So he wanted to take one apart to see if that was true (because nobody ever believes me when I tell them stuff). Instead I figured it would be on the internet somewhere, and sure enough, all I needed to do was go to rippingthingsapart.com to find the pictures I wanted. Pretty neat:

If you unravel the shell of AAAA batteries there are tiny people working inside!
And inside those people are tiny 9V batteries!
Mom might find this silly.
