screens aren't a necessity. but are helpful in not catching that mouthful of ash at the end of the bowl.

waterfalls will chill the hit if the water is cold enough. it won't filter the hit. there is a method to filter a gravity bong which i highly recommend. no pun intended.
BokingTowls Reviewed by BokingTowls on . hello all, advice for a newbie? hi fellas, not only am i new here on this forum but i'm also relatively new to smoking, so i ask you please to bear with me and be patient. :) i just finished my freshman year of college and i'd never done anything of the sort until this semester, but the occasion presented itself three times to experiment and live a little, and needless to say i loved it. like i said, i've only smoked three times in my life and only other people's weed, but i wanna start to make a recreational habit of it, Rating: 5
