Honestly, I'm not stupid, it's like when you guys say " use the search" IF EVERYBODY used the search there would be no freaking forum. I'm also not going to go on google and look at over 150,000 ways to make a homemade bong/pipe, that sounds a little too time consuming, I figured maybe people could share methods they have used.
Isn't there something about this in a sticky? I'm not down for homemade, but it really depends what quality you want. I suggest getting an actual steel stem, though.
