Summer time is great for experimenting, and this is one idea that I’ve been wanting play with more. It’s day 5 for my green beans in a CD case (the 1/4″ thick kind). I want to know when the little sprouts will pop up so they can be labeled and drawn around with poster markers. Science plus art is always a good thing! Stay tuned as I’ll post my finished product in a few days. P.S. If you don’t have any of these cases on hand, you can buy them on eBay for about 50¢. They are made from a plastic that doesn’t break down so it’s especially good to recycle them.
