Have you ever added ice to your bong to make the smoke cooler and less harsh? The Ooze Glyco Freeze Bong has found a way to get that same sensation without having to add ice! Ice will melt as you smoke, raising the water level. No one wants to take a bong rip and have the bong water splash their lips! The Glyco is made of strong borosilicate glass and includes a matching bowl that has a glass screen. Fill the bong to cover the black showerhead percolator. We recommend putting the Glyco in the freezer for at least 1 hour before you plan to light up if you're looking for super frosty hits.
