This week’s dose of woah comes from one of the best symbols of lifelessness and boringness in the universe: a rock.
How could this rock possibly be woah-worthy?
Well, just like with almost every Weekly Dose of Woah, there is more than meets the eye with this rock.
To the naked eye, the rock — composed of oxygen, silicon, chlorine, sodium and aluminium — is blue-grey with white streaks. Because of its appearance, it’s widely used in inlays, but when placed under long wave ultraviolet light, sodalite lights up, revealing the orange-yellow veins that give it an incandescent appearance.
Gem and mineral dealer Erik Rintamaki was on the beaches of Lake Superior, between Whitefish Point and Grand Marais, when he made a curious discovery.
He stumbled across some rocks that seemed to be glowing, emitting a potent glow when exposed to ultraviolet light — they seemed to be partially molten. This is what they looked like under UV light:
Not Rintamaki dubbed them “yooperlites”, a nod to locals from Upper Michigan who are often referred to as Yoopers.
See the yooperlites transform under UV light in this mesmerizing video:
