Reverse Gravity Bong

A reverse gravity bong (or waterfall) is a smoking apparatus that can be easily made with household objects. One of the most widely used versions is one where the user melts a socket wrench piece into the cap of water bottle and burns a hole at the bottom of the bottle, allowing the water inside to flow out, and the smoke to flow in. Weed is packed into the socket piece, and the hole at the bottom of the bottle is plugged. Water is then put into the bottle until it fills up. After, the weed is ignited while letting go of the hole at the bottom. When all the water is gone, simply unscrew the cap and inhale the smoke.
Guy #1: Dude, what should we smoke out of? I forgot my piece.

Guy#2: Let's just make a reverse gravity bong in your garage.

gravitron

A gravitron is the ride at those crappy city to city carnivals that spins real fast. It smells of vomit and sweat and features weight lifting benches on rollers along the wall. Your back is placed upon the bench with you in a semi standing position and the gravitron is activated. Once it reaches speed the benches slide up giving you the feeling of weightlessness. In actuality it is more the centrifugal/centripedal force that allows you to "stick" to the wall.
This guy i work with plans to buy a gravitron and travel the country as a carnie, but we were looking on usedrides.com and they're like $40,000 used!

Graves

A popular grain alcohol, commonly available for $20.00 at most liquor stores.
The catch is that this alcohol is 190 proof, which means that, for those who can do the math, this shit is 95% pure alcohol, higher than over the counter rubbing alcohol. The most amazing part of drinking it is not how three shots can fuck you up to a reasonable degree or the fact that there is a XXX on the bottle, but instead the fact that it leaves your mouth numb and your throat slightly burned if drank straight.
The kind of drink to enjoy when feeling suicidal, but not when you want to hook up, for you will end up passed out on the floor naked with a strong case of whiskey dick anyway.
"Did you get that graves, son?"
"Hell yeah, brother. I'm trying to put dem purple spots on my liver tonight."

Graving

Graving is the hobby of searching out specific graves for genealogy or curiosity of the rich and famous. Also includes the hobby of photographing quantities of grave stones to post on genealogical web sites, or to www.findagrave.com. Some think of this word as a slang word.
In the course of our hobby we would say we are going graving, implying that we will be in a cemetery taking photographs.

Gravity Vortex

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...
