The Cookies Water Wheel Pipe typically has a vertical tube or chamber with a water wheel perc inside. The water wheel perc consists of multiple spinning blades or paddles connected to a central axis. As the user inhales, smoke is pulled through the water, causing the water wheel to spin and creating a visually appealing and functional percolation effect. Water wheel pipes are typically made from borosilicate glass, which is known for its durability and heat resistance. The use of glass allows for transparency, enabling users to see the water wheel perc in action.
