Features:

• 5x increased glass thickness and sturdier packaging
• Lifting is easier and safer with new flange at the top of the bottle neck
• Ground glass joint has replaced the rubber grommet bowl adapter
• Compatible with any 14mm bowl (medium) or 19mm bowl (large)
• Platinum-cured silicone grommet at the bottom for a tighter seal

Usage

Fill the base halfway with water, pack the bowl with dry herb and insert it into the joint at the neck of the bottle. Light the bowl and lift the bottle at the same time. Once the bottle is full of smoke, remove the bowl and place your mouth over the neck, inhaling as you lower the bottle. The Gravitron will give you a dense, pressurized hit with no loss of smoke in the process. While it's considered the ultimate party pipe, the Gravitron is essentially one of the most efficient smoking devices on the market.
