My first thought for this was maybe Second Period uses some type of “cold” laser. When I googled that it brought up cold laser therapy which is not really what I had in mind (and in my opinion not legitimate science). However, after reading this book The Disappearing Spoon I learned that scientists at the University of Colorado created a new state of matter called a Bose-Einstein condensate which they created by cooling (slowing down the movement of the atoms) using lasers. Insane! Really cool book.
