ALL Unschooling Symposium 2012 ✜ December 27-30, 2012 ✜ Albuquerque, New Mexico
There are papers near the cornbags that say this, but here it is for those who miss the paper, lose it or aren't even here. :-)Corn Bag High tech / low tech combination for temporary heat. Two minutes in the microwave (2.5 or 3 for a bigger cornbag), and it will stay warm for a while.If you make your own, use whole corn / seed corn. (NOT popcorn... think about it.) One can last for a few years if it's not overheated. If you leave it in too long, the corn will be scorched and not smell so good. Eventually it will dry out and start to leave dust/crumbs. Not the first year, though!Keep one if you want to. There are enough for each family to take one, and a few extras.
