Maybe you've used a DIY gravity bong before and or heard tales from your elders who've smoked their favorite herbs in the most mind-blowing way. Fast forward a few decades to today and try the Stündenglass Gravity Infuser that works in the same basic way only much, much better. So what is it? It's a sophisticated and elegant smoking device you can use to enjoy your favorite herbs, concentrates, and shisha tobacco. It looks like art and in many ways, it is a functional piece of art in motion. The Stündenglass features two large rotating globes and a base. To use it is simple. You fill the bottom globe with water and leave the top globe half-empty. Then you light the source and flip the globe 180 degrees. This action triggers negative air pressure that pushes the smoke through the falling water into the once empty globe that's now on top, Then flip the globe again so the smoke expels from the mouthpiece for you to inhale.  The Stündenglass gravity bong is a sure-fire crowdpleaser and it's built tough. The base is made from aircraft-grade aluminum, surgical stainless steel, and high-quality Teflon seals. The globes are made from thick and durable glass, plus they're removable for easy cleaning.  The Stündenglass Gravity Infuser is a complete set that includes an aluminum bowl with a 14.5mm male joint, a 3-foot long silicone hose you can connect for direct draws, and an adjustable mouthpiece. Also included is a convenient cleaning kit. The Stündenglass features a futuristic design, it's super durable, and most importantly, it hits like a dream. This innovative and versatile device stands alone at the pinnacle of all smoking and vaping devices known to mankind.
