Take a page out of the Wizard of Oz and enjoy these Tornado Bullet Spinning Carb Caps.
These carb caps have a spherical bottom so they can be moved around to direct airflow and assist in efficient vaporization. Their internal spinning bead creates a visually pleasing airflow vortex that only adds to the experience of smoking, and they measure 26mm in diameter to function with any banger with a diameter less than 26mm.
With courage, heart, and a little brains, you too can revel in these fun carb caps.
