survival kit out of a small metal tin. It is a fun challenge to see just how much functionality you can get into such a tiny space, and it has the advantage of being something you can carry around with you every day. One function it decidedly lacks, however, is being able to carry significant quantities of liquids. Tim MacWelch over at the Outdoor Life Survival Blog solved that by putting a survival kit in a water bottle. While it's a little more difficult to carry on your person at all times, you can easily throw it in a briefcase, backpack, large purse, or bug out bag, and you can put a lot more stuff in it than a little metal tin. I definitely think this is a challenge I will be working on in the near future.
