Airflow and percolation sucks with the tiny cup bowl I switched it out with a different one and I get tremendous airflow. With the tiny bowl I would struggle trying to clear the smoke

This is an amazing little bong. Looks great, heavy glass. Easy to see your hits fill up the base. The bowl that comes with it is tiny, might want to add on a larger one with your purchase

My Grav 8in Wide Base w/Fission Perc arrived at my home within 2 days of placing order. To my eyes it’s a beautiful piece of art. 420 Science is a web vendor which I would purchase from again. Great response.

Just let it rip ! Smooth and classy
