Tim shows how to turn an old refrigerant can into an air can – “Nice for filling up air mattresses, bike tires, blowing dust out of your computer, etc etc. This is a useful thing to have. If you ever get your car stuck in soft sand, snow, or mud, there’s an easy way to get out. Just let air out of your tires til they’re at about 10 or 15 psi. They’ll have a nice big flat spot on the bottom, won’t sink in nearly as much, and you’ll drive right out…” – Link.
