Aside from drinking it - beer has several other uses
..........................................................
ATTRACT BUTTERFLIES TO YOUR GARDEN
Use beer to get some flutter-action in your garden. Many butterflies feed on rotting fruit, tree sap, dung, carrion, urine...this 'butterfly bait' sounds nicer! Mix 1 pound sugar, 1 or 2 cans stale beer, 3 mashed overripe banana, 1 cup of molasses or syrup, 1 cup of fruit juice, 1 shot of rum-and splash on trees, fences, rocks, or soak a sponge to hang from a branch.

BEER RINSE FOR BOUNCY HAIR
The vitamin B and natural sugars in beer add body and shine, while acting as a natural setting lotion that increases resilience, vitality, and hold. Allow one cup of beer to go flat and warm. Shampoo and rinse hair as usual. Pour the flat warm beer on your hair and work it through. Rinse thoroughly with cool water.
For extra shine, try this formula.

REMOVE STAINS WITH BEER
Getting coffee or tea stains out of your rug may seem as feasible as getting water out of a rock, but beer can be a miracle worker in this field. Do a test patch and allow to dry. If it looks ok, tackle the stain: douse it in beer, blot, repeat.
For other types of carpet stains, try some of these tricks

MINI FIRE EXTINGUISHER
For small paper or grill fires. Because of the water content and pressure, you can shake a can or bottle and unleash the liquid on the fire. Some people carry an emergency can in their car in case of engine fire. NOTE: Not for grease fires or electrical fires.

MARINATE MUSHROOMS
Beer works as a great tenderizer that isn’t as acidic in flavour as wine or vinegar-based marinades. Use a hearty-flavoured beer e.g. stout or barley wine, poke a few holes in the meat or mushrooms, add any other herbs or spices, and allow to marinate in the refrigerator for a few hours or overnight.
................................
POLISH COPPER POTS
Just dampen a soft towel with beer, and buff! In the past, dregs of beer from spent kegs were used to polish the copper vats in breweries. Because of beer’s subtle acidity, it can help boost shine without staining the metal like a higher-acidity liquid would. Do a test spot first.

BUILD A PATIO WALL,
and more, from Beer Bottles. Many handmade houses have employed empty beer cans and bottles, like the one pictured here, built by Tito Ingenieri (Argentina), which used 6 million beer bottles! Perhaps you could adapt the idea to build something at home, e.g. a retaining wall or a screen for a patio.
