Subsequent models have had similar problems with the hole either being too small or too large, and there seems to be some general design flaw as far as the internal chamber is concerned. Note the common color scheme of red and green, the colors of bong that belonged to my parents that had to be hastily disposed of during the Bust of '96 which I still have not been able to satisfactorily replace or recreate.
Funky vases or purely ornamental objects, but sadly no good for getting high.
