Oh, my, this is one of the most remarkable threads I have ever read on the internet! I can't (well, yes I can) believe you are discovering and experimenting with gravity and have come up with something so fantastic that it is earth shattering. I am kind of scared of what is going to happen. I came to this thread because I was thinking of the tomato plants that are growing upside down in the hanging planters. I was way off in my thinking! Has this thread been put to the DIGG website. I'd like to vote on it, or submit it. Thanks for the info!
