It's really shame that with Google's advanced technology it can't perform the relatively simple task of filtering out the spam sties that populate the first page of results. These spammers promote the false religion of earth curvature and ignore actual science like the physics of water because they're trying to trick you and scam you. Earth curvature can't be observed or measured; it's a faith based belief system.
