Harrison Krix of Volpin Props has made a replica Gravity Gun from "Half-Life." As awesome as that is, what's even better is he's auctioning it off for charity. That's right, you can get your very own gravity gun. Just stay away from the old passage to Ravenholm. We don't go there anymore.
In the 2006 Christmas Special, "The Runaway Bride," the doctor created a diversion by causing an ATM to spit out money. The prop money used in the show were 10-pound notes with David Tennant on them and 20-pound notes with producer Phil Collinson on them. Now the BBC is letting you print out your own.
