A "Better" Idea

I was just wondering if anyone has a better idea for creating a way to make 12V from the small 1.5V hearing aid batteries that erco had on his deal of the day a few weeks back. I bought a package of the 100 batteries. So far, the best way I have come up with is to stack 8 of them end to end on a magnet and then use silicon to encase them. Anyone have any better ideas for this? Yes, I have thought about parafin but do not have any on hand. I am looking for solutions that can be made from household items. Tape works but is a pain for a good seal.

    Good one. I have plenty of it. Thought about a straw but not quite wide enough. Some times the simplest things are right in front of you and that is what makes this forum so great!!!!! Thanks.

    Be sure to use the magnets to keep them snug while you heat the shrink. :D
