Product Description

The Grav Labs Gravitron is the world's first affordable gravity smoking system. You won't make a grav bong like this in your college dorm room with random parts.

Available in your choice of 11" and 14" height. 

The Grav Labs Gravitron consistently produces very potent hits. This is caused by the water drawing smoke into the bottle at a rapid pace. The water is not filtering or cooling the smoke in any way. To break things down a little further, it is essential to understand the whole process of using a gravity bong.

First, place the bottle into the empty glass cylinder. Once the bottle is in place, fill the cylinder with water until it is about 2 inches from the edge. Next, insert the dry herb bowl into the mouthpiece. Then, simultaneously as you light the dry herbs, slowly lift the glass bottle. This will draw the smoke into the bottle. Once the smoke has completely filled the bottle, remove the bowl. Keep your hand steady once the bowl is removed, because any downward movement will force the smoke out. Place your mouth on the mouthpiece, and slowly push the bottle downward while inhaling. If you're new to gravity bongs, start out with a smaller amount of dry herbs and work your way up.

No smoke is wasted when using the Gravitron correctly. Made from thick and durable scientific glass, you will not have to worry about your clumsy friends dropping it. In case any of the parts on your Grav Labs Gravitron break or malfunction, there are many replacement pieces available. Label color may vary.

Awesome product, needs tweaking

This is the classiest gravity bong I’ve ever owned. BUT it doesn’t create a very large hit whatsoever. There also needs to be either a better rubber piece, or a redesign on the bowl. When smoking, I have to hold the bowl down onto the bottle to seal it and get the apparatus to pull. Also, with nothing to grab onto the actual bowl with to remove it from the bottle, it’s nearly impossible after lighting and smoking it. Because of how hot it is. I have been using tweezers to grab and remove by the base.

The rubber piece that fits onto the bottom of the bottle is also waaaaay too large, creating a large “fold.”

Moral of the story, beautiful piece, but many design flaws.

Poor performance

I bought this bong, being a little nostalgic to my beginning days of smoking. The first Time I tried to use it the stem piece shattered when I tried to light it. On top of that, the bowl piece doesn't fit flush with the stem so it doesn't provide a solid hit unless I'm pressing as I light it. I was really looking forward to this piece and am very disappointed with my purchase.
