The idea is to get a plant with white flowers, water it with food-colored water and watch the flowers turn colors. So I got a white phlox flower, we planted it and have been watering it with blue colored water for a little over a week now.
I should have known better to touch plants. I have such a brown thumb. Guess Bella will have to be content with pictures of what it should have been. Good concept though, if you don't kill everything you touch. :)
Have you ever set out to do a nice science experiment with your kids (or by yourself) and have it go terribly wrong?
