Laser Maze
The signature Laser Maze from Laser Fun Day 2019 at the University of Arizona College of Optical Sciences, run by the Student Optics Chapter (SOCk). Student volunteers pose in the maze in this six second exposure. The laser powers are kept very low in order to keep them eye safe for the hundreds of visitors who attempt to cross the maze without setting off the alert lights. Two smoke machines give the laser beams ample opportunities to scatter, making them visible despite the low beam power.
