Well im not doing this thing to make moe, i did this thing becuse some were doing it so complicated with drilling and stuffing pipes with cement to drill exact holes, wich seems to have taken some time =O)

I did just take a simpel plastic tube and heated it up in the middel and the pulled voila 2min of hard work puh...and i did some diffrent sizes =O))

I did an experiment now in the evening and since we are using pressurerised gas( we really dont need the sucking) when the gas bobble came out it was sort of vaporised out of the venturii so they seem to work =O)) BUT when there were no bobble it was just shoting ......water =O)
If it will work in long term i dont know, but for 2min of work and some cheap plastic tubing it was easy.
