Ice Attachment to a Bowl for Easy Toking

right now i have a pretty awesome elephant bowl, its made of glass and can pack about 1.5 grams in its piece. You pack the piece in its back, hold the tail (rush-hole) and hit from the trunk. I wanted to know how i could go about building a DIY ice chamber with maybe tubing attached that i could simply slide over the trunk of my bowl so i can take luxury ice hits without blowing the cash. I'm thinking maybe like a soda can or bottle with plastic tubing. the material its made from doesn't matter cause the flame and heat are all in the bowl so this is all just extra.

tupperware and some rubber tubbing. make two holes for your rubber tubing to fit snugly into. fill about half or more with water and ice or just ice place tubing under ice water (or ice) an one above.
