4. Magnetic Hill (Ladakh, India)
Magnetic Hill isn't an album by French electronic artist Jean-Michel Jarre, but a mountain pass in Kashmir's Ladakh where gravity is said to behave backwards. Motorists who cut their car's engine on any part of the 30km highway stretch will find themselves saving a load of petrol, as their vehicle spookily begins to roll uphill - potentially reaching a cruising speed of up to 20km/h.
Some say a supernaturally strong magnetic force surrounding the road is at work, which makes sense since cars are made of metal. Even aircraft have been known to avoid the zone, lest their equipment succumb to scrambling.
Locals have a more mystical explanation: the Magnetic Hill used to be the the road to Heaven, with those deserving pulled towards Paradise by spiritual powers.
What both these theories have in common is that they're absolute hokum, designed to entice disbelieving tourists. The actual explanation is that a curved or obscured horizon creates an optical illusion, making a downhill slope appear to head uphill.
Or, yeh, magnets. Why not?
