Am I allowed to ask... how much would he normally charge?

He doesn't sell them, so $0.

i have something called a "mistmaker" not sure of the real name,
but it is the things in fog fountains found in chinese restaurants.



HAs ceramic plate that vibrates/breaks the water apart into a fog.
i wonder if this might work in a similar way, and more affordable.

if i put a finger over the jet, it feels like all my finger cells are going to explode.

i will try this eventually, if only because it will look cool to have a misty brew.

That wouldn't be powerful enough to lyse cells. I have one of those. They probably only use a couple watts of power and it only messes with a very small spot of water just right above the plate. When a sonicator is going off it makes this crazy squeal and the entire solution goes crazy and stirs around. It's very powerful.

Ultrasonic cleaner bath? They exist industrial but also for household purposes.

Though I'm afraid they have not enough punch for the job we're looking for, they are cheap and work with "a lot" of liquid.
