If you're using a glass pipe you don't even need a screen. I actually picked up this little tip by posting a similar question in these very forums when I was starting out.

You just stick a larger nug at the bottom of the bowl, so you don't suck it all into your mouth but smoke can still get through... no need for a screen with a pipe. :thumbsup: :jointsmile:

With all this talk about aluminum foil bad for you, arnt the pipe screens aluminum also? i used to you aluminum foil until i noticed i could melt it with a bic lighter.. and saw fumes... so none of that, i hope these screens are steel, Rating: 5
