I wanna hit bowls in my room so can i just use tinfoil and poke little holes in it to substitue for a filter?
put a big nug at the bottom so nothing falls through the hole an then break up some weed an put it on top of that.
Use a little stone or pebble to block the hole, as long as it isnt rounded, it will still allow smoke to pass though.
Nope...tinfoil no good. Gives bad fumes... Joint is good...pebbles work nice, too... Edit: If you unscrew your faucet tip, you'll find several screens in there...just use one of them...
