Somewhere AJ heard that he could grow green onions in a jar with water. For the past month we have had this weird experiment happening on our kitchen windowsill. He thinks they are growing, but I think they are the same. The onions are beginning to look creepy and gross, a little bit Alien. At what point can I throw this experiment out? Or do I need him to come to his own scientific conclusion that the experiment is dead? Any hypothesis of your own?
