1. Put Out a Fire
Although certainly not as effective as a real fire extinguisher, a can or bottle of beer can mimic one if none is available. Simply shake and spritz. After all, beer is mostly water. This works on small grill flare-ups, and some people have been known to carry an emergency can in their car in case of engine fire. Or at least that's what they tell the state troopers.
2. Shampoo Your Hair
Not only is beer the remedy for a dull party, it's also the cure for dull hair. Dump a cup into a small saucepan and bring it to a boil over medium heat. Let it reduce until there's 1/4 cup left. This removes the alcohol, which can dry hair. Let the beer cool, then mix it with a cup of your favorite shampoo. Pour it into an empty shampoo bottle, then wash and rinse as usual. It'll give your hair more shine and luster.
3. Pass a Kidney Stone
As you've undoubtedly noticed, beer is a diuretic. It helps flush the kidneys and bladder. This can be beneficial if you're suffering from a bladder infection or kidney stone. "You can drink water or cranberry juice, but beer also works," says Larry L. Alexander, M.D., medical director of Central Florida Regional Hospital's emergency department. " It helps dilate the ureters [the tubes connecting the kidneys and bladder], which may help you pass a stone quicker and easier. Plus, the alcohol will take the edge off the pain." But don't drink beer if you're taking antibiotics or narcotic pain medications. You'll render the drugs useless and make yourself sick.
4. Kill Slugs
Gather a few empty salsa jars (or similar wide-mouth containers) and fill them a third of the way with cheap beer. Then bury them about 15 feet from your garden, girlfriend, or whatever you're trying to protect. Make sure the rims are almost level with the soil surface. For some reason, slugs love beer. They'll find the traps, drop in, and drown. Do this in the evening, let them party all night, and give them an honorable burial in the morning.
5. Build Your Home
Earthship, a house in New Mexico, has walls made of empty beer cans and concrete. Amy Duke, a spokeswoman, explains that instead of using forms for the cement, builders put down alternating layers of mortar and cans. You can do the same to create retaining walls for gardens and other landscaping. Earthship also contains a thermal-mass refrigerator that uses full cans of beer as insulation. The cans line the walls of the unit, helping keep the temperature constant while minimizing energy usage. A ceiling vent allows frigid desert air to flow in during the night. The beer absorbs this cold, but never freezes because of its alcohol content. When the hatch is closed during the day, the beer releases the coolness. The same thing happens when you open one and drink it. Read more here...
