Hey this is my newest creation it hits like a monster. it has a 5 arm tree perc, inline A/C, diffused down stem, Ice catch, its also almost 100% air tight, the only place on the piece that isn't is the slide but its close enough. You can also completely dissemble it because all the pieces just screw into the lids of the vitamin waters. The inline looks a little sloppy but i had to tape on the wooden sticks to support the weight because the straws weren't strong enough. I post some better pictures of the tree perc later. The diffuesd down stem, i'll post some better pictures of this later as well. I also have a normal ash catcher that you can use for it aswell. and they are both slides, so there is no carb. The rest of the sections of the bong can also be dessembled for easy carring too.
