""Anti-Gravity Hills" (also known as "Gravity Hills", "Spook Hills", or "Magnetic Hills") are natural places where cars put into neutral are seen to move uphill on a slightly sloping road, apparently defying the law of gravity. Typically, the "spooky" stretch of road is rather short (50-90 m), only a few meters wide, and surrounded by a natural hill landscape, without nearby buildings. Such places are found in several countries all around the world, and have been tourist attractions for decades. They should not be confused with the "Mystery Spots" [previously] found in amusement parks. These are generally tilted cabins, purposely built as such; a person walking inside feels disoriented, getting a very strong impression of standing at an angle in a perfectly normal room." CSICOP and Discovery News explain the phenomenon, and here's the paper on which the CSICOP article was based (PDF).

"UNTIL you experiment with chlorine, you have missed some of the biggest thrills your home laboratory can give you." Sound like fun? Bet you'll want to set up your own home chemistry lab and try it out. But don't stop there - the wonders of hydrogen and mercury await! Make a gas that gives you the giggles, then blow stuff up for more guffaws. And that's just part of only one section of Modern Mechanix - "Yesterday's Tomorrow, Today!"
