Made from borosilicate and boasting 4mm thick glass, the Fierna is as sturdy as it is impressive. At 35cm tall, the bong has a nice weight and size, making this the perfect pack-up-and-go bong.
It also has enough extra features to make any blazer smile, including drum perculators, diffusers, glass screens and ice notches.
The bong filters the smoke in several stations, starting with the slit diffuser adapter – which the herb bowl with fixed glass screen is plugged in – the smoke travels through a dome percolator into the next chamber. There it meets a drum percolator which ensures more swirls and more bubbles.
Because of the lots of small bubbles, the surface contact with the water is already enlarged when it arrives at the third station. There is a cylindric slit-diffuser which produces even more bubbles. Ice notches (don’t forget to add your ice-cubes!) add a final cool to every hit.
