When I think of batteries, the words "fun" and "amazing" definitely don't come to mind. After watching this video of battery hacks from Rick Lax, and if these are indeed true, it will change how I think about batteries forever.

In this YouTube video, Rick Lax turns what seems to be a solid drinking glass into a squeezable substance in only 12 seconds using vinegar and a D battery.

Every wonder what's really inside of a 9v battery? No? Me neither. But, if this video is true, a 9v battery is filled with 6 AAA batteries.

I'm definitely going to investigate these on my own and I'll let you know what I find out.
