The Gravity Bong - Grape

A gravity bong is a smoking device that harnesses gravity to pull smoke into a chamber, delivering powerful and highly concentrated hits. It usually consists of two main parts: a larger container filled with water and a smaller chamber that fits inside the container. The smaller chamber holds a bowl on top where you place your herb, allowing smoke to build up as the water creates suction.

A gravity bong operates by using air pressure and water displacement to deliver smoke directly into your lungs. To use it, you place your herb in the bowl attached to the top of the inner chamber, which is submerged inside a larger container filled with water. As you light the bowl, you slowly lift the inner chamber, creating a vacuum that draws air through the burning herb and fills the chamber with smoke. Once the chamber is packed with smoke, you remove the bowl to reveal the mouthpiece. Then, by gently pressing the chamber back down, gravity and water pressure push the smoke upward, allowing you to inhale a smooth, concentrated hit.

Unfortunately, no bong is immune to the sticky resin buildup that naturally accumulates with regular use. Over time, this residue can affect the flavor, smoothness, and overall performance of your gravity bong, making cleaning an essential part of maintaining your device. Fortunately, the Weeday modular system is designed with ease of maintenance in mind. Its fully disassemblable parts allow you to access every nook and cranny, making it simple to remove resin buildup before it becomes stubborn. Regular cleaning not only preserves the purity of your hits but also extends the lifespan of your bong, ensuring a consistently fresh and enjoyable smoking experience every time.

They provide strong, concentrated hits and can be a cost-effective alternative to other smoking devices.

Common materials for DIY gravity bongs include plastic bottles, glass jars, or specialized glass pieces designed for durability and heat resistance. High-quality gravity bongs, like Weeday’s, tend to be made from borosilicate glass that can withstand daily use for years to come.
