What is perc angle?

The term "perc angle" refers to the angle between the perc water level and the top of the perc downstem on a water pipe or bong. Perc is short for percolator, which is a device that filters smoke or vapor through water to cool and smooth it out. The perc angle determines how much water is required to reach the perc and how much smoke or vapor is filtered through it. Different types of percs have different angles, including 45, 90, and 180 degrees. The perc angle can affect the overall smoking or vaping experience, with a steeper angle generally providing a stronger filtration and smoother hits, while a shallower angle producing more flavor and less filtration.
