As opposed to those "heady" style rigs that feature an opaque body completely obscuring the function of the piece, this piece features sleek, clear, "scientific" glass that allows you to watch this rig function. And you'll want to watch this rig function because this functional snowglobe features an ornamental snowman right inside! But it's not all just looks, this globe bong features some of the most tried and true water filtration methods available on the market. Take the functionality of the classic "ball-style" rig and add a showerhead perc for maximum water and smoke diffusion.
