Well you could go to the head shop and buy a pack of screens..
Or to the hardware store, I think you can get small screens that are meant to be used in plumbing.
But I'd say screens made for use in bowls are best, and certainly cheapest!
stinkyattic Reviewed by stinkyattic on . Screen? So I got a homemade water bong that ive been using for a while. It works real good but every now and then, but not often ill take a hit and a little bit of weed will fall through because i dont have a screen. I dont know what i could use for a screen so got any ideas? Rating: 5
