Description

The Gravitron is GRAV’s original gravity bong and the piece the company was built on: a glass bottle inside a glass chamber of water. Lift the bottle as you light and it draws a full chamber of smoke; push it down and it delivers all of it at once. It uses a 19mm joint with a 19mm funnel bowl included, and is offered in Medium, Large, Monarch and the Breathe Again edition.

Why it stands out

• The original all-glass gravity bong — no plastic bottle, no cut-up jug
• 19mm joint with a 19mm funnel bowl included
• Four sizes and editions: Medium, Large, Monarch and Breathe Again
• Delivers an entire chamber in a single push

Specifications

• Joint: 19mm

Care

Empty the outer chamber after each session; standing water in a gravity chamber clouds the glass quickly.

Good to know

Gravity bongs deliver far more smoke per pull than a standard bong — start with a small bowl until you know the piece.
