GAUZE

Most toking devices (buckets, falls etc) need a gauze on top. In weed shops you can buy gauzes which you can put on your device. Here are two ways of making gauze.

socket gauze
every cunt has a socket in their shed or somewhere, just pick one which fits nicely on to your bottle, buy some gauzes, and put the gauze in. this acts as a notch vacuum for pulling healthy buckets.

tinnie gauze
Just get some tin foil from your kitchen and shape it onto your bottle, pressing it down to make a hole. Get a pin and prick holes in it. This will do the same job as a socket but not quite as well.
