Since 2002, the MythBusters have used science to separate fact from fiction but now, after an epic 14 years, that wild ride is coming to an end. In this special episode, Jamie and Adam reveal what's in store for their go-big-then-go-home final season, while also pulling back the curtain to showcase how this epic series got made with behind-the-scenes exclusives.

This season, Jamie and Adam try something they've never done before: an Implosion caused by a vacuum. The tall tale goes that a freight train tank car was being steam cleaned when a rainstorm let loose. The engineers made the mistake of sealing the container full of hot steam and headed home. The rain cooled the tank car, the steam condensed and contracted, and the resulting pressure differential caused the massive steel car to crumple like a soda can. Is it possible? The MythBusters devote an entire episode and embark on the biggest logistical operation in their history to find out.
