The Triple Jellyfish Perc Bong is Pulsar's stacked-percolation piece: three jellyfish percs running in series. Each stage breaks the smoke up again before it reaches the next, so by the time it gets to you the pull is cooled and smoothed further than a single-perc piece manages. That's the trade — more diffusion, more to clean.
99, best for the flower smoker who prioritizes a soft pull over simplicity. The three jellyfish percs running in series provide stacked percolation, and each stage further cools and smooths the pull.
