My mist loopback venturi (pic&movie)

I've created a somewhat different and very easy to made mist-reactor that works better than my previous efforts.

Main differences are
1) no vortex, just 750 l/h straight down.
2) a fine 180 degrees cut by a scalpel that spread the bubbles evenly
3) closed bottom
4) loopback high up instead of further down
5) high pressure inside the reactor making the venturi-loop shoot water without the need of suction

Made by a 750 l/h MaxiJet and a 0,5 litres PET. I tried a 1000 l/h MaxiJet, no difference except the flow from the cut was so strong it blew plants down.

No gas buildup and mist all over the tank when I direct the 180-cut into a corner underneath my Fluval "lily-pipe".
