Rainbow Prisms

I gotta choose a science project by tomorrow. It's kinda like those science fair ones, except we actually don't have to enter it, but you can. I reaallyy can't find a nice one to do. Googled science fair projects, but those didn't work. I need a project that could have manipulated variables and stuff. So this morning, our teacher took some books from the school library that had to do with sciency stuff. I found, in a kiddy book, some of those awesome experiments that you always wanted to do. You know, the volcano aka baking soda and vinegar, and this soap bubble one. But, I wanted to do something with a prism. Not the geometry one (cuz I'm really sick of geom), but those rainbow making ones.



I always wanted one of these, so this is an excuse. Who wouldn't want to hang one of these by your window and make their room all rainbowy...at least for girls. Guy rooms are too messy....no offense ^^
