Throwing a glass pipe (Pyp Prometheus Titan) on gravel

I needed another break so I decided to throw a Pyp Prometheus Titan around for a while. I have thrown this one around quite a bit, used it to fix my deck, and dropped it off a cliff. There are scratches in the aluminum from where it hit rocks, I've had the bowl break a few times (easily replaced), but I've never had the tube break yet. I'm actually surprised considering how much abuse it's taken.
