This is the replacement Aqua Bubbler for the Randy’s Chill vaporizer. It provides portable water filtration and comes in handy when your regular tube isn’t chilled. When the bubbler is filled with water it makes the vapor cooler and smoother. Be sure to replace the water regularly. The Aqua Bubbler is made from handblown borosilicate glass and is 3” in length. This glass piece is easily cleaned with 99% alcohol or any of the Randy’s Cleaners.
