10 Money Savers for Mom

Remember all those childhood birthday presents your mom bought you that also required her to stock up on cartons of double and triple A's? This cute clock allows your mom to cut back on wasted batteries. It runs on water (or any electrolytic fluid, such as soda, coffee, or beer); its internal converter extracts electrons from water (or other liquid) molecules to produce an electrical current. Pop a few daffodils into the water reservoir, and you're sure to be Mom's favorite. It measures 6 inches tall by 4 inches wide by 2 ½ inches deep.
