2005 What is a perculator?
perculator (?perc? for short) is basically an additional
water chamber found in the main shaft of the bong tube.
Several companies use different designs, but they all
focus on more water to smoke interaction, making for a
better filtered and cooler hit. Some of the better known
companies take it a step farther by adding diffusers
into their percs, which basically break the smoke up
into smaller bubbles making a cooler smoke.
is an example of a 3-chambered Phx trinity.
What is a diffuser?
is another type of downstem for a bong. Contrary to a
downstem, a diffuser resembles a test tube as its sealed
on the end or pierced with many small holes or slits.
These slits break up the smoke into smaller bubbles than
a normal downstem.
Why the need for smaller
bubbles? The smaller the bubbles, the greater the
surface area of the smoke that contacts the water, thus
filtering and cooling the smoke more efficiently. This
makes the bong almost silent silent. Many glass
companies sell diffusers to fit their bong: Roor, Phx,
Here is a pic of a german Roor
diffuser along next to a Phx diffuser.
