A 20-inch color-changing double bowl glass ice bong with a 50mm diameter is a large and visually striking piece with advanced features. Here’s what you can expect:

• Material: Made from high-quality borosilicate glass, which is durable and resistant to thermal shock. The color-changing feature typically comes from fumed glass that reacts to heat and light, changing color over time.

Design:

• Color Changing: The glass changes color with use, providing a dynamic and personalized look.
• Double Bowl: Equipped with two bowls, allowing for simultaneous use or the ability to switch between different materials easily.
• Ice Catcher: Includes ice notches to hold ice cubes, cooling the smoke as it passes through for a smoother inhalation experience.
• Size: At 20 inches tall, it offers extensive smoke cooling and filtration, ideal for larger sessions and deeper hits.
• Diameter: The 50mm diameter provides ample space for smoke to accumulate, ensuring bigger hits and effective cooling.
• Base: Designed with a wide, sturdy base (often a beaker or round base) to provide stability and prevent tipping.
• Percolation: May feature additional percolators or diffusers for enhanced smoke filtration, resulting in smoother hits.
• Mouthpiece: Designed for comfort, ensuring a pleasant smoking experience.
