Is there a Water pump that can pump one bead of water in the air one at a time?

Hello:

I realize this is a very random question, but I am wanting to retro fit a water pump to shoot one bead of water in the air one at a time, instead of a steady stream of water.
This is for an indoor project and there will be no fish involved.
I just want to have the motorized pump in water and have the ability of the pump to shoot one bead of water in the air one at a time. Not that high as the height doesn't matter.
I can make the water stream from a pump thinner, but I can't get it to shoot one bead in the air at a time.

Any help is appreciated.

David

The pump is the power and that's the easy part. What you need is control to make the one bead/shot of water. Just a part of it you will need a fast acting valve to create that nice, crisp beginning and end to the stream. If you want on long, smooth stream you'll need laminar flow as much as possible.

I remember the fountain displays in Las Vegas where they sequenced those short bursts of water into some very dramatic displays. As Pilot said, it is the fast on/off control that will give you your bead of water. The pump will simply provide a constant pressure.

Thank you both. I appreciate it. Now where to find a fast on/off value control, hmmmm

It's going to be somewhat experimental to find a solenoid that works as you need.
Just looking around I found this.... Solenoid-Normally-closed-Crack-resistant-U-S-Solid

Another though I had is maybe a water pump for a fish tank.

Pete, that's what I have, and I can make the stream a thin bead, but I can't make it into a single drop.
I need a spring plate to cut off the flow and then open it and close it fast to try to get a drop/small stream, but I can't figure that out either, haha.....
I can put my hand or a plate over the flow and move it into and out of place really quick, but that's all I got, haha,.....

The closest I've seen is our local museum and a Kyoto-sister city park, which feature a single-drop into one focus of an eliptical pool, which generates waves that reflect back to create a standing wave-vertical water drop at the other focus.

So, it IS possible to use a vertical drop INTO an one focus of an elliptical pool to create another drop at the other focus. I wonder if the laws of hydraulics and momentum would mean that a MOVING drop into one focus would generate a drop with corresponding momentum at the other focus?

Other ides, create a single-drop drip at suficient height and use a hydrophbic channel to redirect the drop where you want it to go?

Only other time I've seen individual drops manipulated was by using sound waves to create-and-accelerate single water drops.

Run this Google "solenoid to create pulse water" Seemed to find a lot of solenoid control valves.
