Photo of the Day: Optical illusion in Las Vegas

Las Vegas has a way of turning the ordinary into the extraordinary. Case in point: today’s Photo of the Day taken by Flickr user Gustavo at the City Center entertainment complex. In the photo, monochrome lines and angles look more like a work of minimalist modern art than what they really are: balconies at a hotel.

The Truth Behind “Gravity Hills”

According to Wikipedia, a gravity hill “is a place where the layout of the surrounding land produces the optical illusion that a very slight downhill slope appears to be an uphill slope.” The video above investigates a gravity hill just outside of Burkittsville, Maryland (also where the Blair Witch Project was filmed). The legend of this particular gravity hill goes that the ghosts of the dead soldiers of the Battle of Crampton’s Gap push your car or skateboard uphill. Actually, it’s just an optical illusion. Watch the video to see how it works.
