if you want a small bubbler get a pack of mentos gum put 2 holes in the top. put part of a straw through 1 of them and hot glue it in place, then hot glue a ratchet head to the straw. now put the other part of the straw in the other hole and hot glue it in place. fill it half way with cold water, pack your bowl (ratchet head) and hit that shit.
