Just so you all know.
The blue precooler, that first one is broken. Doesnt have the male end, just a glass tube. and the second is bieng used with an 11cm (its a 10cm length ashcatcher) diffuser, but it is working perfectly. The whole thing is completely air tight, and is without a doubt THE best smoke i have ever had in my whole life. That bieng said, I have only just recently goten into bongs.
made from parts of mine and a friends bong...

had a really good night!!
