Mold for making tool out of ice

Abstract

The present invention relates to an elastic mold for holding and freezing a liquid. The mold is constructed of unitary construction and comprises of one or more walls and a base, wherein said one or more walls form a compartment. A plurality of protrusions extend upwards from said base. The liquid held in said elastic is frozen into the shape of a test tube rack.

I claim: 
     
         1 . An elastic mold of unitary construction, comprising:
 one or more walls and a base forming a compartment to contain a liquid, wherein within said compartment a plurality of protrusions extend upwards from an upper surface of said base, and said plurality of protrusions are spaced apart from said one or more walls, and said plurality of protrusions are spaced apart from each other, wherein said liquid can flow between said plurality of protrusions and said one or more walls, and said liquid can flow between adjacent protrusions.   
     
     
         2 . The elastic ice mold of  claim 1 , wherein one or more said plurality of protrusions extend upwards from said upper surface of said base to below a height of said one or more walls, or wherein one or more said plurality of protrusions extend upwards from said upper surface of said base to a height of said one or more walls, or wherein one or more said plurality of protrusions extend upwards from said upper surface of said base to above a height of said walls, or any combination thereof. 
     
     
         3 . The elastic ice mold of  claim 1 , wherein said compartment is a single undivided compartment. 
     
     
         4 . The elastic ice mold of  claim 1 , wherein said compartment is divided into one or more compartments by a dividing wall or multiple dividing walls of unitary construction. 
     
     
         5 . The elastic ice mold of  claim 1 , wherein said plurality of protrusions have a cylindrical, rectangular, square, or cone shape, or any shape consistent with the shape of a test tube, or any combination of said shapes thereof. 
     
     
         6 . The elastic ice mold of  claim 5 , wherein said plurality of protrusions have a shape of a cylinder, and said cylindrical protrusions have a diameter consistent with a diameter of a test tube. 
     
     
         7 . The elastic ice mold of  claim 1 , wherein elastic material is any elastic material suitable for placement into an environment capable of freezing water, and wherein said elastic material retains elasticity below a temperature of negative 70° C. 
     
     
         8 . A method of making a test tube rack out of ice, comprising the steps of:
 obtaining a mold of unitary construction, wherein said mold has a compartment appropriately shaped to make a test tube rack out of a frozen liquid, filling said compartment with liquid,   placing said mold into a freezing environment at a temperature at or below the freezing point of water,   waiting for said liquid to freeze to a solid state,   removing said mold from said freezing environment,   removing said frozen liquid of a shape of a test tube rack from the mold.
