Customer Reviews

Great for chromotography Review by Tina

The filter paper worked great for our chromotography experiment with leaves. We tucked the paper in the cup with bits of shredded leaf and rubbing alcohol and the colors in the leaf moved right up the paper. It was a great way to show the 3rd graders the colors in the leaf they couldn't see. (Posted on 4/14/13)
