It doubles a player! I'll let you in on a secret about how it works: the player you drag into the machine drops, but there's a secret platform inside the machine that another player is attached to. I've addded a sensor that, is removed from the game when the drag-player touches it. then, both players(the player which was inside the machine's link to the platform is deleted because the platform has been deleted) fall out, appearing that the drag-player
has been doubled!
