beads of water floating on water.

these are not air bubbles. they're water beads floating/sliding around on water surface.

I used a nosehair trimmer(i lost the blade) and turned it on and put the spinning peg against a 591ml bottle of pop (except half-filled with water).
The turning peg vibrates the whole bottle and creates a pulsating effect and drops of water would jump out from the sides and slide around on the water surface while remaining beads of water.

Not sure why the pulsating surface is keeping the drops of water from combining with the water below.

Accidentally discovered it once when i was watching Star-Trek on TV one time long time ago, when i would tap on a 2-litre pop bottle (half-filled with water) then when the TV went to commercials, i'd stop tapping the bottle and looked at the bottle and noticed drops of water shrinking in volume (losing their volume to combine with water below the surface) and I was like "wtf was that? and then i tapped again to repeat and drops would form from the side and slike around on the surface so long as i kept tapping at a constant frequency, the drops would maintain their volume and slide around and as i stop tapping they lose their volume at a rate that you can see the shrinking in size.

I ran into a youtube video that demonstrated the same thing with an actual equipment set up and adjustable frequency, and I was like "hey, i totally saw that with my own hand tapping" but this time i used a smaller bottle and a much faster pulsater (nose hair trimmer, i'd imagine it would probably work with an electric tooth brush as well - i meant battery operated toothbrush) but not sure why this time i don't see the drops losing their volume slowly, but very quickly (quicker than i can see), not sure if it's the frequency and surface area of water in a smaller bottle make it disappear quicker probably but i don't know enough about science to explain why those drops are sliding around when the water is pulsated).

What's weirder? is when some of these water beads combine when they touch long enough (maybe 1/2 - 1 second) and form a larger bead but they won't combine with lower water unless i stop the nosehair trimmer or move it away from touching the pop bottle.

What i am not sure about is if the pulsating waves are depositing water into the spheres/beads at the same rate as water that's combining with the lower water or if these are actual beads that are sliding around with their own surface tension that won't break so long as the waves/pulse remain active.

In any case, here's a video of that water on water action.
