used battery ideas

wasnt sure bout where this should go but any one got any ideas about what to use (used) triple a batterys for?

I dont really want to throw them out as im thinking bout toying round with capaciters and seeing if i can make them explode (for robotic purposes of couse, small ultra bot comes to mind Twisted Evil ) but before i go and blow my stock of used batteys up any other use you guys can think of?

Deliberately exploding a steel cylinder full of toxic cadmium (assming they're NiCd Batteries) creating flying metal fragments probably isnt the smartest thing to do, but hey I did it when I was young and stupid too.. Wink (although I only did it with watch batteries that make more of a POP than a bang).

How about buying a bunch of those ultra-low current flashing LED's that will run for years off a single cell (even when flat), and creating some form of art sculpture and call it "Das Blinkenlights" or something ?

A bit more work that just blowing them up, but you get to keep something you can be proud of more than scars, burns or blindness..
