I've heard about that method! [It's an easy experiment to pull off. Akane doesn't mind Flat's company. He seems nice. ]

This is a different test. You put a drop of food coloring inside the roots. Wait a day or two and the plant will change colors! I need to make sure the color's going down the plant stem first.

Soo... I'm watching it with a microscope. Come take a look!
