Hi,
Is it possible for a car to physically gain speed, going up a hill without any other forces other than natural magnetic fields and gravity supplying the propulsion? You'll be amazed.
There's a hill here called the "Magnetic Hill", I didn't believe it at first but some unscientific experiments later, the car does actually roll up the hill and gain speed. Its tough to believe it but it's true, it does happen, and no I'm no where near bermuda triangle nor am I smoking weird substances.
