Ohhh, yeeaaah. If you’re looking for the most efficient smoking device out there--you found it. Not a spew of smoke goes to waste in Grav Labs’ landmark Gravitron. Maximize the power of their one-of-a-kind design with this XL design. For some of us, this is a throwback to stealth backyard smokes, but there is nothing makeshift about this scientific 16-inch glass piece. Simply fill the base with water, load the glass funnel with your favorite legal herb, and oh-so-slowly pull it up for a natural siphon effect. You’ll witness the herb transform itself into a deep, dense cloud that just can’t be imitated with carcinogenic plastics. The best part: lift your glass bowl away and inhale as you push the bottle shape against the water for one intense experience. Grav Labs puts its stamp of quality and authenticity with an etched slide and sleek logo decal. One go on this Gravitron and you’ll be telling all your friends!

As smooth as it is cool

This is an amazing bong! Also super easy to clean!!! I was considering a more traditional bong (ie beaker) but the customer experience team at DopeBoo referred me to this one and I honestly couldn't be happier. Best bong ever -- this baby!!!!

Love this piece!

It's got a bit of nostalgia for me, but more than that I get killer hits. Great for parties!

A gravity bong without the fuss

I always loved gravity bongs, and this is just like the old school homemade ones, except I don't need to piece it together everytime I want to use it!

So glad someone finally made a professional version of the gravity bongs we used to use at high school and college parties. It's similar to those, but way more efficient and easy to use!

Cool with guests

Definitely a cool piece to have in your arsenal. I pretty much only use it when I have some friends over and we are looking to relive our glory days.
