Not only is the automatic dishwasher more energy- and water-efficient than washing by hand, it's also the best way to kill germs and bacteria. So it makes sense that you can use your dishwasher to get other things clean, too. Try running your kids' toys through the dishwasher; think non-porous things like plastic building blocks, action figures (with clothing removed) and even the rubber ducky from the bathtub. And don't forget pet toys. Those toys live in your best friend's mouth, so a designated rinse in the dishwasher will get them clean and ready for the next game of tug-of-war.

Since 1987, the UNICEF program Change for Good has raised more than $120 million through the collection of leftover foreign currency on international flights and at airports and airport lounges around the world. If you have a collection of unwanted foreign currency, collect it and bring it with you the next time you fly. Any American Airlines Admirals Club Lounge will accept your spare change for the program, regardless of whether you are a member. All of the funds raised are used to help children in need.

Man's best friend also needs protection from the sun's harsh rays. If you're planning to spend a lot of time outdoors with your dog, consider applying sunscreen to his snout. Since your dog's coat acts as a natural sun protection barrier, it's the non-fur areas -- like the snout and part of the underbelly -- that need SPF the most. But be sure to choose a sunscreen that has no zinc oxide. This chemical is toxic to animals, so check labels carefully. If you think your dog has a sunburn, give him a cool water-only bath and apply natural neem oil to the coat, which helps heal burns.
