I probably shouldn't be telling you, but I have in my possession a magical container. It's a small after shave container, and I don't think it can ever be emptied. I received the bottle as part of a shaving accessories gift over two years ago - the bottle is now still half full. Admittedly, I don't shave everyday - rather about 3 times per week. Usually a bottle of aftershave will last maybe 6 months - this one is still going strong after 4 times that - over two full years. I apply this stuff generously too, at least in the past year. I probably should get some NASA scientists to check it out, perhaps it's alien. I have considered filling it with expensive wine or something, to test if the bottomless effect applies to substances other than aftershave. I will post the results of my experiment.
