I just saw the coolest thing on I Want That!. Solar Safe Wristbands go on you and your children before you go out in the sun. When you apply sunscreen, apply it right onto the wristband. When the wristband changes color, reapply the sunscreen. When it changes to a lighter color, time to go inside. When you know the color is right, you know you are safe. I love this idea, and thought it would be expensive but worth it. As it turns out, they are at Drugstore.com for less than one dollar each.
