new way to cover bowl

[NERV]

while i wait for my new bowls from sean i have been toying around with
my current bowl, if i use the screen then the seal isnt as good so the
smoke isnt as thick, if i use foil then it tends to come real close to
burning and the screen vibrates a bit and ashes get inside the bowl
making it hard to clean, but i have figured out a neat way to get the
best of both, i put the screen on then i get a big sheet of foil and
carefully press it over the bowl to perfectly fit it and seal around
the sides with the foil,then poke out the holes in the screen thru the
foil, it ends up with a good foil seal and a safe solid screen underneath
