High functioning science beaker from Zob Glass out of California. “Instrumentum Percolatus” is their moniker as they make science glass with insane function through elaborate percolation. Speaking of insane functionality – this is their fixed stem with a flat disc or showerhead perc on the stem made out of solid 5mm tubing. You come out of the beaker base and go into Zob’s UFO perc – which is a precision made and shaped dome perc. Then you have a nice splash guard perc that sits below ice pinches at the base of a generous ice chamber. If you fill that with ice, or even better crushed or snowcone ice your pull is like a cool arctic breeze. 14mm high quality snap bowl comes with. This bong has beautiful yellow Zob labels, also ‘Calimade’ as they are proud to be American glass made in California. Fantastic work from Zob!
