Hello all, just watched this video where YouTube creator Tech Ingredients demonstrates triboluminescence using rock candy he makes. I noticed during the slow motion footage of the demonstration, some visual artifacts appearing on the footage that seemed to be timed with the flashes of UV generated. Could this possibly be artifacts caused by Xray emissions interfering with the camera sensor during the fracturing? Appreciate any insight, and hope everyone has had a great weekend.
