Speaking of vortex, the second listing from the first seller of the tall ratchet fountain klein recycler, with all the color options (including a rainbow metallic one) for $42-46, actually has a
great function video revealing pretty perfect cyclone tornado vortex function in the klein funnel... In the green color, tried to snap an action shot:
I also found a couple other listings, from different sellers, with a variation on this design, that is about an inch shorter smaller, mostly the mouthpiece, the piece is more clear with color options for the tubes and accents... One was expensive but
this one is reasonable round the same price, and with another function video... Though I like the full colored transparent glass look, and that matches the two I already have for dabbing!
So yeah I'm very close to pulling the trigger on the teal version from
BONGLAS (aka RadiantGlass) after seeing the function video, along with a three pack of directional carb caps (in matching colors for the three rigs) so I can use those smaller bangers...
And I also discovered Radiant actually have the proper version of this tall spiked tube, with the slitted cube perc, instead of the shower head ratchet perc on the versions I found at glass99 and kokokoko, while it is also much cheaper than those versions:
