Mechanicville woman says she and her husband were struck by something fired by someone in a passing car at Park and Third avenues in Mechanicville. Katrina Osterhout tells WNYT, the shooter appeared to be a boy wearing a red bandana covering his face. Police believe it could have been a gel blaster shooting water-based gel beads called Orbeez. Teens across the country are taking part through social media in something called the Orbeez Challenge, driving and shooting the guns.
