Is that small crack, nick, or gouge all you can see each time you look at your dark wood dresser? Reach for the instant coffee. Mix 2-3 tablespoons with just enough water to make a thick paste; for wood with red tones, add a few drops of iodine. Put the paste on a small putty knife or a disposable plastic knife and use it to fill the crack. Remove any excess around the edges with a barely damp cloth. Let the paste dry completely, then buff with furniture wax.

Here's a handy tip from Mother Jones. Turn a coffee can into a grill by cutting some holes into the metal bottom and a "moderate size" triangle into the top. Flip the can upside down and throw some kindling—dry pine needles, for example—into that triangular space and light. Once the metal bottom is heated up, add meat and veggies.

It isn't the caffeine in coffee grounds that plants like azaleas and rosebushes and evergreens love but rather the acidity and aeration the grounds provide—not to mention nitrogen, phosphorous, and trace minerals. Just be sure to dig the grounds into the soil to keep them from becoming moldy. But don't overdo it: Dig about 3/4 cup of grounds into the soil near the roots, repeating once a month. Fertilizing even acid-loving plants with coffee grounds too frequently could increase soil acidity to undesirable levels.

Some pet owners have found they can remove pet odors from a room by heating a cupful of freshly ground coffee beans in a cast-iron skillet over low heat. As soon as the scent is released, remove the pan to the smelly room and set it on a trivet. By the time the ground beans are cool, much of the pet odor should be gone.

What are the holidays without strings of lights, and what are fresh-out-of-storage cords of lights if not tangled? Grab an empty coffee can and its lid. First, slice the plastic lid of the can with a sharp knife and insert one end of the cord. Then wrap the cord of lights around the can, taping the end to the can to keep everything in place. Before putting on the lid, fill the can with extra bulbs and an extension cord. No tangles, no misplaced accessories.
