So here's something wonderfully simple & cheap that my kids absolutely ADORE. When I'm having a lazy mom day, instead of busting out all of the normal bath time toys that I loathe fishing out from the bottom of the bathtub every time, I toss in a package of glowsticks that I got from the dollar store & turn some of the bathroom lights off. My boys LOVE this! I know these aren't great pictures, but they give you the general idea. I wish the pictures did more justice to how much the glowsticks really make the whole bathtub & water light up though. I like it just as much as the boys do!
