We've already seen how one laser creates a window to the past... now Cassie's using a different type of laser to project a window into the future.
TRANSCRIPTION COURTESY OF JOSEPH HOUK - (CW continues, in her car) I began to wonder, "Is this what I think it is?" I didn't want to cause a commotion at the workplace, so I went in on the weekend to research this further. I took my car-window hammer and carefully pounded on the metal rock until it had a smooth, cone-like crater. [BANG BANG BANG] Then I took a different laser and pointed it at the new crater. [The first rudimentary time machine!] After setting up a camcorder to tape my experiment, I fired up the laser. This time it generated a larger ring, one that I could easily fit through. I noted the time on the wall... [Analog clock reads 2:27] ...and walked into the ring. Coming out the other side, I glanced at the clock again. It had jumped 83 minutes ahead. [Analog clock now reads 3:50] And as I played the video footage back, the reality set in... [A very, VERY shocked Cassie] ...I had TRAVELED THROUGH TIME.
