Can some one inform me about how the ice wall around the earth works. I am working on a school project and I cannot find any information on the ice wall. I need to prove it to my classmates because they are globe-earthers. How tall is the wall? Why can’t planes fly over it? Why has nobody gone over the wall? Any information anybody has would help a lot. I completely believe in the flat earth and the ice wall, but I don’t have any proof. Please help me!
