You're electrical question is easy- lick two fingers... Seriously, you can get a good multimeter for about 40 bucks. If you or someone who might need your kit doesn't know how to use one, you can get a little plug tester. It's mostly used to check wiring, but it will tell you if you have current and if you have too much, while warning you if you have a bad ground.<br><br>With your canned soups and veggies, don't forget the instant rice if you can cook. You might not think about it, but the rice will give you extra food, if you use the cooking water of the canned goods, and you won't loose any value from veggie water. Add it to any kind of soup or gravy (water it down some), and you're in business. I know that instant chicken gravy and rice doesn't sound like much, but it might be better than nothing.<br><br>And forget about containing cooking smells in an apartment building, unless the septic goes. That is the only smell that can cover food smells.
