How do you create batteries out of toilet paper?
How much could you sell them for?
That's a good question, Dee, but over my pay grade. I'm sure Howard, Tim, or Floyd would be able to answer that one. I would just try to paint the cardboard tube with Lithium colored paint and see if that would work, but no guarantees. The TP itself would just be considered packing material. Useful stuff in some circumstances, tho.

PS: What color is Lithium? I hope it's not purple or mauve...I hate those two colors.
