I suspect the world would be better if that percentage were even greater.
Using Geraniums as Photo Paper
I have seen lots of wacky science projects before, but I hadn’t seen this one before. Basically, the idea is to project a bright image onto a geranium leaf. Where light stricks the leaf, the leaf will produce excess starch, which can be “developed” with tincture of iodine. Crazy. I may have to give it a try.

If you’ve lost your digital camera and you need to take a picture, as a last resort you might try a bright light, a geranium and a bottle of tincture of iodine. link (ht: brainwagon )
