The perfect bong has a wooden cone/piece/köpf and there is a fine iron screen on the bottom of it. It's the bong screen and it is a very important part of a bong.
Such screens can be found in hardware stores or can be simply removed from household water taps.
They need to be cleaned after a few rips, but they can last quite a while and are worth its weight in gold.
