Mine is a huge colorfull trophy tube. No duct tape anywhere, everything fits perfectly. Also, if you want it to be cooler, you can make a slide carb. The way I did it was by cutting a clear pen, that was about the same size around as a crayola marker, cut down to about an inch. I winded the end a bit so the socket could just fit in with a little [ok, a lot] of effort to get it in. Then, I found another clear pen that was a little bigger than the slide. [Make sure it's long enough though, so you can have more water to cool the smoke.] It slides in and out smoothly, and the bowl keeps it from going in. It's really a beautifull piece, homemade wise.
