The coolers can be assembled by wrapping silver duct tape (110) about a five gallon paint bucket, followed by a coiled layer of spiral wrapped copper tubing (120), followed by another layer of duct tape, followed by a layer of foam type insulation tape, followed by a layer of liquid foam or foam inserts, where the assembly is created inside of a compartment box or is placed into a compartment box.
