The Right Pointing Arrow, taken directly from @physicsfun on Instagram, is truly a special thing:⠀

“Right Pointing Arrow: posted one year ago- this video had physics so hard to believe that Snopes fact checked it- verdict: not fake! (of course) Spin this arrow 180 degrees and it still points to the right- only in a mirror will it point left (and only to the left). An incredible ambiguous object illusion by mathematician Kokichi Sugihara of Meiji University in Japan, the inventor of this illusion and art form. A clever combination of reflection, perspective, and viewing angle. ➡️ Follow the link in my profile for info about where to get this illusion arrow and other amazing items featured here on @physicsfun”.
