If you like the smell of coffee, but have some that you don't want to drink or some used grounds, pat them dry and then put them in a bag or a small bowl in the back of your fridge. The smell of the coffee will do wonders to freshen — or at least cover up — any other unwanted smells inside.
Instructables user mikeasaurus, formerly of pizza cones fame, has 11 unusual uses for coffee, but this one is particularly interesting. He uses a nylon sachet to store a bundle of ground coffee in the back of the fridge, but we figure a small bowl will work as well if you don't have a porous bag to keep the ground coffee in. The coffee will dry out slowly in the cold and moist fridge and as it does, your fridge will smell a bit like coffee until it's completely dry.
It doesn't actually absorb odours like activated charcoal or something else more potent would, but it does give you fridge a delightful coffee smell that will wake you up every time you open the door.
Do you have any other unusual uses for ground coffee that's no good to drink, or coffee grinds you're through with? Some of Mike's other uses include composting and palate cleansing, but what are yours? Let's hear them in the comments below.
