Float your kid's boat: Create a faux river running through your yard with a hose and some heavy-duty aluminum foil. Unroll two layers of foil to your desired length, and fold their outer edges up to create a path for the water to flow through. Turn the hose on low and let your child sail water toys merrily down the stream.

Try a Bright Idea
Let your little one play the punk while school's out with temporary hair dye made from unsweetened Kool-Aid. All you need is: sugar-free Kool-Aid in any flavor and paper or plastic cups.
Mix the Kool-Aid at a ratio of three to four times the usual mix in hot water.
Place the concentrated Kool-Aid into cups and have your child dip the tips of her hair into the cups while the Kool-Aid is still warm. The longer the hair sits in the cups, the more vibrant it will become (you'll need at least five minutes for the color to show; ten for a brighter hue). The color change will be more dramatic for lighter hair and may only show up as a slight tint on dark hair.
Rinse with clean water, but do not wash with shampoo for 24 hours. The color should fade after a few weeks, depending on your child's hair color.
Make these water toys for hot days. Cut sponges into strips 1 inch wide, gather nine strips together, and secure them at their center with a sturdy hair elastic. Then fan out the strips. Soak with water and let your kids toss them at each other.
