also note if you want a cheaper option, http://thermovape.com/collections/all/products/glass-adapter-kit is a different material either will stand up fine, I just prefer the white teflon. When your going to use this, you can either keep that tube really long and keep the inh004 beside the pipe, or cut a small section so you can just rest it on top of the bubbler, will be kinda top heavy but work for you if your laying in bed, you could have two different sizes. The little plastic white or black piece (whatever which one you decide to go with) bigger end goes into the water pipe opening, (fits in either 18mm or 14mm) and leave the tubing on the smaller end sticking out which the inh004 capsule fits right on the other side nice and snug! Use the 'SUMMERTIME' 25% off discount when you check out! It ends this Friday. Imagine in that picture your inh004 is that vape on the left and it was connected to a bubbler on the right. Hope this helps!
