The GRAV Monarch Gravity Bong is a scientific glass tabletop device engineered for the water filtration of dry herbs. Designed by industrial glassware expert Micah Evans, this unit relies on vacuum pressure to draw heated air through a packed bowl, accumulating concentrated clouds within its clear internal chamber. Designed for individuals seeking a precise inhalation method, it features a decanter-inspired profile with a heavily scalloped body. This unique texture provides a functional, slip-resistant grip for safely operating the device. Supported by a 4-inch wide base for stability, it is constructed from dense borosilicate glass.
Vacuum-Powered Water Displacement
Operating differently from standard water pipes, this gravity pipe utilizes physical movement and water displacement to function. By filling the outer glass base with water and pulling the inner bottle upward, the user creates an internal vacuum. This automatically draws air through the funnel bowl without requiring continuous inhalation, effortlessly filling the chamber with dense clouds before pushing the inner bottle down to force the contents through the glass mouthpiece.
Decanter-Inspired Scalloped Design
Created by industrial designer Micah Evans, the heavily scalloped body serves both structural and functional purposes. The textured glass exterior adds distinct visual elements while acting as a reliable, slip-resistant grip. This ensures users can safely grasp and lift the inner glass bottle during the vertical movements required for operation. The elegant decanter shape is supported by a 4-inch wide base specifically engineered for tabletop stability.
Dense Borosilicate Glass Construction
The entire unit is manufactured from thick, dense borosilicate glass, a material known for its high resistance to thermal shock and structural integrity. A platinum-cured silicone grommet effectively seals the gap between the inner bottle and the outer base. This component maintains optimal suction, preventing any unwanted air leakage during the vertical extraction process. It includes a 14mm male funnel bowl that holds approximately a half gram of dry herbs.
