Yea, I was surprised how thick it was too. It's def thicker than the f-bomb. I don't know about how the 2 pieces differ quality wise when it comes to glass, as I'm not versed in that field. Maybe someone could chime in on that. (the box that the PNWT came in said..American made scientific glass and All scientific cuts are fire polished)
The bomb is slightly slimmer and taller than the PNWT..
The difference in the thickness of the mouthpiece rim is even more pronounced (PNWT on top) I kinda like the way the thicker rim on the mouthpiece feels, although the f-bomb's mouthpiece doesn't feel bad or anything, just a minor preference.
Here's how the top level of both tools looks close up.. (bomb first)
Bottom levels..(bomb first)
Bomb gets filled to the middle of the M
I like filling the PNWT up to the bottom of the A/top of the C, otherwise the bubble feels too 'weak' as if there's not enough water (is not enough drag the proper term ?) That same amount of water will fill the bomb way up past the bottom of the first B (obviously WAY too much)
So the PNWT def has a lot more water volume capacity. Now you don't have to put as much water in the tool as I do, but as I said before, if I just filled it up till a little past the slits the bubble feels too 'weak' to me.
The Bomb on the other hand, when filled to the middle of the M (which isn't too much higher than the slits/holes at all) has even a deeper bubble (more resistance/drag?) than the PNWT when its at the bottom of the A)
I know it's kind of hard to see the slits on the bottom of the tools, but the ones on the PNWT are a little larger and there's more of them too. The little tube all the way in the center of the tool (don't know what it's called) is a little longer in the bomb.
The pics of the top of the tools show the bomb has 4 horizontal slits (2 at the bottom and 2 towards the top. That piece also comes alot closer to your mouth, than on the PNWT. The PNWT has 3 vertical triangular slits on the bottom, one bigger than the other , 2 horizontal slits directly on top of those and one more on the other side by itself.
