The Gravity VORTEX is the world’s first portable gravity smoking device that hits like a gravity bong and is smooth like a vaporizer. Winner of the gold medal at the 2006 High Times Cannabis Cup, the VORTEX is quickly taking the smoking world by storm.

As the water drains, filtered smoke fills the top chamber, clean, cool hit that wont hurt your lungs. Its made of high quality poly carbonate, so its virtually indestructible. Perfect for dorm rooms, outdoor adventures, and small enough to put in your backpack and bring to a party.

It is very easy-to-use and fun for parties. You only have to use a small amount of product to get the same effect as a vaporizer. Everyone will have a fun time watching the physics drain the water to the bottom chamber, while at the same time pulling a 2-liter bottle size gravity hit. The days of messy bottles and buckets are over.

In addition to being a fun and social way to smoke, the VORTEX is endorsed by the medical smoking community for the therapeutic benefits it provides. Patients now have new relief and comfort for their illnesses.
My friends and I all got together and smoked this new GRAVITY VORTEX.

Pass me the Gravity VORTEX...

Good for 2 weeks until it's dirty and uncleanable. Wasted $200 on a bong you can't clean and only usable for 2 weeks. Plus, you suck up air through the down stem and suck up resin to my lungs.
Dude, that gravity vortex is grimey!
