Hello!<br><br>I am curious to see what kinds of containers can be found in nature that would be able to boil water. I am primarily interested in the things that could either be found or made in the United States region.<br><br>The most common things I know of are not very useful in a temperate North American climate, ie: bamboo, coconut shells, etc.<br><br>In the past, I have heard that certain kinds of bark would be useful. The problem is that it either burns or leaks.<br><br>If anyone has success stories in this regard, I would love to know!<br><br>Peace and God bless America<br><br>Chris<br><br>
