I bought a Zong Bong about 7 or 8 years ago and to this day it is the most awesome thing I have ever smoked out of. That thing would never ever disappoint. It was a color changing twist model, it was about 2 feet tall. After getting a few good years of use out of it my dad found it one day in my closet and that was the last time I ever saw it. I remember how hard I pleaded with him to not destroy it so I could get it back one day when I wasn't under his roof anymore. I've been out of his house now for a few years and still try to get the balls together everytime I see him to say "Sooo Dad, you remember that awesome bong you took from me way back when..."
That bong took a training session to be able to clear... I got to a point where I could do it everytime. I also had a little 10'' strait Zong Bong that I loved to death, it was without a doubt the most smoked from pipe in my house. Anytime I wanted to get high and didn't want to smoke a whole bowl in one hit, I'd break out the mini Zong.
I remember ordering the larger bowl upgrade for my big Zong, because you realy did need a bigger bowl for that monster and because I remember the day I got it I took it into the bathroom and was marveling over it in the mirror and dropped the bowl and shatard it. That sucked.
I don't think the original makers of the Zong Bong are still around. I remember one day there site just dissapeared. You can still buy knock offs and you can find originals aftermarket, but I don't think the original distributer is still in business. I hope I'm wrong, someone please post a link for me and make my week.
