Using the same science that is applied with gravity bongs, it introduced a 360° rotating glass design with a tough make and stunning black aesthetics that it is sure to grab your attention. It is also designed to be a triple threat, which means you can consume your green herb, concentrate, and hookah; a pretty all-in-one accessory.

The glass chamber is allowed to rotate 360 degrees, almost like an hourglass. Oh, and interestingly enough Stündenglass means "hourglass" in German. Pretty smooth, isn't it?

It is quite simple to use, just fill the bottom container with water, leaving the other half of the glass empty. Once you light it up, you flip the glass chamber 180 degrees, causing the negative pressure to pull the smoke through the waterfall into the empty chamber, which is now on the top.
