took a can of planters nuts. Punched two holes in top (enough for the tubing to fit snugly) in. Hot glue gun is optional it will make it air tight. Inside of the can is ice cubes that go to the top tube goes to the bottom of ice. Then another tube is where you draw from. You get smooth ice cold hits. you can do this with a coffee can or any other canned food with resealable plastic top. btw on top of my buddah is a glass candel holder from the dollar store. It works just as good as the 25$ one.
