Ah, much clearer with pictures, yes, thank you. I think I'm going to see if I can find a can that I can do something similair with for use with nalgenes.

I hate it when I go to the grocery store and everyone is looking at me funny becuase I'm measuring the cans. Of course I could always mutilate a an olicamp cup, but I don't want to do that. :P

What are you using to fuel your trangia? I've been using the yellow HEET and I can get 500ml of water to a rolling boil in about 7 minutes with it. I'm wondering if your juice might be better, or if boil time vs volume isn't a linear relationship.

I also didn't see a fuel bottle in that kit.
