Last night, big sis and I were posting outside the backyard talking. And i told her about the forums and some of the threads. She's a teacher. I mentioned one of the threads something about a metal ring surrounding the earth. Will it fall or float? She said it'll float, i asked her why she thought that and then she went on and on about the gravitational pull, if the ring was positioned in a certain way, it's possible that this and that will happen. I'm thinking to myself, how the hell did she come...
