haha thats some juvnille shit. all of it water bottles come on!!! a bubbler outta a cheezz ums barrel and some metal tubeing. the best bowls for home made pieces are rachet heads or door stops those springy things. put a sharpie in any bottle then the door stop just slides in. whala u got a slider

double triple even quad chamber bongs are what u guys need to be makin. biggest hit u will ever take

My best homemade bong was a 12oz big mouth micky bottle. It was almost spill proof too, rubber cork on top with two holes. One hole with pull bowl and the other had a tube sticking up.

I also has a mouth/nose gask mask i would occasionally hook to it. Strap it on and stright hit after hit. I don't think the mask was such a safe idea but it worked.

my shower head was metal with elbows and looked like a crack pipe. so my friend and i smoked out of it. once. it tasted like stale water and calcium.

gas mask with a tube and a bowl...cover the end with your
hand like a steam roller...its brutal.

Not a bong, but good DIY idea.

one time I took a small mason jar and and some surgical tubing and a 3/4" socket and made a bong out of all that. We called it the "Nad" short for Grenade. It would hit f*cking hard.Hence the name. Just used a drill for the surgical tubing and the bowl...I think that I used a piece of small diameter ready rod and two nuts to hold it to the lid.high temp silicone stuff to seal everything up.Wish I still had it, it was awesome. Thats the craziest bong I ever made..

wow i was expecting some better/crazier ideas. Where i live for gravity bongs are real commen and like everyone had what we called a gb piece which was just a little socket wrench through like a deer park bottle cap and you could just carry it and find a bottel and make waterfalls. But one night i had the idea to tape pen tubeing to the socket wrench on the side that went into the water and when you did a water fall like the vortex gravity bong it would bubble as it when up smoothing the whole thing. Like you would pull the most crucial hit and be like shit that is like so dark yellow smoke its going to suck, but then you just inhale and you felt like you got jipped because it wasnt nearly as crucial as it looked. But anywho i remeber hitting one then going to class and i was in orchestra and the bridge of my violin fell off and my teacher was fixing it. Oh also it had a 16mm socket wrench bowl with some really dank jack herer i got from my friend. But this all happend like with in a minute of me smokeing the fall so my teacher is fixing it and asking me all these wierd fucking questions as the high was comeing on but i thought it was funny becasue it was like a count down like i walked in sober and finally when he was done i walked away from him BAKED. Also i made a double chamber bong out of one bottle once by haveing it like normal bottle bongs but instead i cut of the cone part of another water bottleand cut a bottle in half and glued it in the middle. Then the pen tube goes in the bottem chamber you ahve made with the bowl. Then you get another cone piece of bottle and rest it on top of the first one you put in with the cap on but the bottom ones off. This is confuseing but bare wiht me. Then you glue the whole bottle togther agian and pour water in the top cahmber you ahve made but not enough it goes down the cone part of a bottle down into the bottom chamber. So the second chamber bubbles from all around the cone piece like a ring of bubbles of smoke already cooled from the chamber benieth. But anyways that is my 2 cents.
