The Double U-perc Beaker is a crazy bong. The way the U-perc works is unique and fun to watch. These suspended percs hang upside down in the chamber and water stays tightly within the enclosed percolator. The U-perc combines maximum water filtration in a small space with not much water. The result is double filtered hits that move quickly through each chamber with minimal drag.
