He said he built a room he showed a pic of, as a floating mall, when it's actually one floor on a hirise building. He showed another pic of what was supposed to be floating, but is an island, and he claimed he did more than that, and never proved it. He's shown pics of two islands and said they floated. He gave a pic of the Marshall Islands radioactive containment dome and said it was a floating sphere. And most recently you showed a pic of a semi-submerged volcano peak in Hawaii and he said it was an example of nature building an island or some such nonsense.
Oh, and there's no proof he ever launched that black submarine, and doing so would be illegal in Columbia. I could go on and on, but don't feel like spending the time.
