The Invention is an apparatus and method for charging a dry ice drinking vessel with dry ice. A dry ice drinking vessel has a dry ice chamber communicating with an interior of the dry ice drinking vessel through perforations. A body selectably holds a filter in engagement with a perforation of the dry ice chamber. Liquid carbon dioxide is discharged from a pressure vessel through a valve and flashes into carbon dioxide gas, a portion of which freezes to dry ice. The carbon dioxide gas and dry ice flow through an orifice into the dry ice chamber. The dry ice is prevented from leaving the dry ice chamber by the filter. |
