Want to freak your guests out at your next box social? Pick up a few of these unique ice trays that form ice in the shape of dentures. Drop some into a gin and tonic, serve it up and watch the horror unfold. After all, the slogan for Frozen Smiles reads “not your grandfather’s ice tray.” How witty! If you added just enough red food dye to the ice tray, you’d probably have some realistic looking teeth going on.
