I almost forgot to mention our rainbow catcher.It's the CD and old credit card pieces you see hanging in the window.Everyday between 10 and 11 oclock we watch as the CD catches the sun! This makes a beautiful rainbow (yes, we also know it as a prism)on the wall. We even have a rainbow song that teaches us "all the colors that we know,are up in the rainbow".Parents this a great way to put those old scratched up cds to work.All you need is a window that gets sun light,some string and thumb tacks.Nature does the rest!
