She also used cans as curlers.
This is can art and there are thousands of examples of things you can make for the sake of 'art' from cans on the web. From soda can spinners to tin men to guard the yard, you can find photos of anything in a Google image search!
For my purpose in this blog, I would like to take making things from cans back to the prepper.
These spinners are good just as they are as scarecrows in the garden. If you make a tin man with a free moving armature, wiring the arms with a little slack and hanging it, it too can make a scarecrow as long as it moves and clanks.
For the bare bones prepper, a can is an organizing device, a storage device, a source of metal to cut, shape and secure into other shapes.
However, for the home crafter, you can't say "make from a tin can" without posting pictures of an illumination.
Crafters know to either fill the can halfway with water and freeze it before punching holes into the can, or keep it's shape by shoving a piece of wood scrap in the can before punching.
You can make a nasty shive from a can. Other cutting tools and knives can be forged with a good cutting tool and a tin can. Right now, tin can material is quaint or crafty, but a knowledge of using and some experience in making without cutting yourself, can help in the future should raw materials become hard to get.
If you have never considered making anything from a can, go to this site and take a starter course.
This site shows how to boost your wi-fi, a project I will try in September (family trip coming up!).
When we all run out of aluminum foil and want to bake potatoes you can put the potato in a can that the lid is still attached to, bend the lid shut and leave at the edge of your fire's coals to bake.
Cans are good to keep, if you keep them clean. There's no sense in ever attracting bugs to the home front.
Store some with prep items in them, and when the time comes, when you are short of raw materials, use them to build a better world.
