@larry_laser: These super cool glass sculptures seem to have infinite reflections inside of them That's achieved with a clever combination of mirrors, lights, and glass shaped ao that it causes total internal reflection Total internal reflection is that if light goes from glass to air at the right angle, it doesn't transmit through it like normal amd instead bounces around the inside of it Having some extra internal reflections before being able to leave creates some of these illusions Optical engineer Cory Boone breaks down weird optics facts and how light is used to do amazing things in these short, educational videos Introduce a kid in your life to science and optics with the Larry Laser kids' books, available through Amazon and the publisher SPIE's website! #optics #physics #Science #stem #engineering
