Over the Christmas holiday I flew to my folks, and in route, was given a water bottle by a flight attendant. I looked at the neck and saw the optical qualities that I thought could be used to make a fire. Sure enough, when I returned home I gave it a try and it worked. Sometimes “bigger is better” so I tried a 2 liter soda bottle in the same manner with great results. So, I decided that it could be illustrated by video, and you can now view it at Metacafe. Check out my video description for more details.
