Terp balls are used to help completely vaporize every last bit of product added to a banger during a hit. This 100ct tub from White Rhino is filled with glass terp balls that come in different colors, and their newest option glows in the dark! Also called terp pearls, just add one or two to the banger before the process begins. The ball will heat up with the banger and will spin around the banger on a strong inhale. This will push the residual liquid around, essentially slurping them up.
