Earth Swallowing Black Holes. When physicists first flipped the switch on the
Large Hadron Collider (LHC), at least a few people held their breath. For years,
rumors had circulated that the particle accelerator could create mini black
holes that would destroy Earth. In 2008, a group even filed suit to stop the
particle collider from turning on, arguing that the atomic collisions could
cause the end of the world.

Zombie Dogs. In 1940, Russian scientists released a video of severed dog
heads that were kept alive for several hours, wiggling their ears in response to
sounds and even licking their mouths. The scientists claimed they could keep the
animals alive by an artificial blood circulation system.

Mind Control. Talk about a bad trip. In the 1950s, the CIA launched a
top-secret program called MKULTRA to look for drugs and other techniques to use
in mind control. Over the next two decades, the agency used hallucinogens, sleep
deprivation and electrical shock techniques in an effort to perfect
brainwashing.

Bat Bombs. In World War II, the U.S. Marine Corps worked on a project to
train bats as kamikaze bombers against the Japanese. A Pennsylvania dentist,
Lytle Adams, first proposed the idea to the White House in 1942, after visiting
the bat-filled caves at Carlsbad Caverns in New Mexico. The Marine Corps
captured thousands of Mexican free-tailed bats and developed explosive devices
to strap to their backs. The project was scrapped in 1943, probably because the
U.S. government had made progress on the atomic bomb.
