Don Salvador Benedicto's Rolling Uphill Illusion

Spook or science? Thirty four kilometers up Bacolod City is the famous Don Salvador Benedicto KM34 marker where a strange occurence happens.

Called the "rolling uphill illusion", it is a visual trick that makes things seem to roll upward an inclined plane when actually it is rolling down.

This video demonstrates how our mini van rolls up about two meters without a driver.



Here are two more links to show you how spilled water would drip uphill in the same area.

The locals, though, would like to believe that the area is enchanted, sometimes causing accidents despite the wide concrete highway.

That's how science can still be spooky.
