The nonprofit Kids Time helps cheer up the hospital rooms of sick children across the country by giving them whimsically decorated wall clocks. Kids in the Boys and Girls Club or scout organizations assemble the clocks, and more than 3,500 clocks have been donated to date. To make the clocks, donated watches are upcycled and incorporated into the design of the clock. Twelve wristwatch faces are glued over the larger clock's numbers to give it personality. You can empty your jewelry box, junk drawer and dresser of broken or unused watches to Kids Time. To learn how, just visit kidstimeclocks.org.

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.
