Without comment, a sad story from Russia, as at least 12 ravers suffered partial to near-total blindness from a laser show being put on for their entertainment.
Okay, one comment. The article says
Attendees said heavy rains forced organizers to erect massive tents for the all-night dance party, and lasers that normally illuminate upwards into the sky were instead partially refracted into the ravers’ eyes.
Technically speaking, the word they wanted was ‘reflected’, not ‘refracted’. Classic case of wanting to use a more sciencey-sounding word rather than the one which was more accurate. Still, sad story. Don’t mess with lasers, boys and girls!
