Think you can walk in a straight line, blindfolded? Guess again.

Here's a fun experiment to try next time you find yourself in an open field. Close your eyes (or wear a blindfold) and set off walking, taking care to walk in as straight a line as possible. Have a buddy monitor your route (and warn you of obstacles). Sounds simple enough, right? Turns out it's harder than you think. »9/25/13 1:40pm9/25/13 1:40pm
