Coral Castle was built from 1,100 tons of coral blocks by one man, Ed Leedskalnin, over 28 years. How did he do it? Some say he used unknown advanced technology like magnetic vortices.

Skeptoid answers student questions about the safety of menthol cigarettes, antibacterial cleansers, missing time reported by UFO believers, zero point energy, and the ability to sense when you're being watched.

Some people listen to binaural beats (computer generated rhythmic audio files) in the belief that they can induce desired brain states, like a drug, or like an instant superpower pill. In this episode we look at the claims and at the actual science.

Some say that a 700-foot hill in a small village in Bosnia is actually the world's largest and oldest pyramid, connected by a network of subterranean tunnels, and demonstrating a level of workmanship that predated and was superior to the Egyptians. We point our skeptical eye at the Bosnia Pyramids.

Kangen and other similar companies sell machines that purport to "ionize" or alkalize your water, claiming a huge range of fantastic health benefits. The only problem? None of it has any remote scientific plausibility.

You probably know most of these, but you won't know all of them. Some popular characters from history were real, and some were fictional -- but who really knows which were which?
