Stündenglass — “hourglass” in German and owned by vaporizer company Grenco Sciences — takes that ingenuity and creativity to another level with its gravity hookah, made of borosilicate glass and aircraft-grade anodized aluminum. Glass gravity infusers propelled are by kinetic energy. The Stündenglass is easier, and less risky, to use compared to the traditional gravity bong. There’s no anxiety of ruining your weed by getting it wet, the mechanics of the Stündenglass allow for smooth, flavorful hits every time. It’s also exponentially classier than using a literal bucket and jug. In an age where cannabis consumption involves apps and haptics, it’s a breath of fresh air to use something more analog that’s just as science-y. Seeing gravity work its magic and fill the Stündenglass with smoke felt like I was in charge of a cool adult science experiment. The base is incredibly sturdy, meaning you won’t tip anything over while you’re flipping the glass. The smoke is smooth and easy to ingest, and the high from it is body-encompassing. The Stündenglass fills with enough smoke to share between two people for a comfortable high, but if taking a single, very large hit is more your style, Stündenglass can accomplish that without destroying your lungs. The versatility of Stündenglass is also impressive. On top of using it with flower, hookah, and wood chips, you can also attach a dab rig — either an e-nail or a regular banger — to the device. Overall, the high you get from Stündenglass is cleaner than one from a regular bong.
