BAKING SODA!

Water sinks in oil, then flashes to steam, violently displacing the oil, oil that's already near or beyond the vaporization temperature. The hot oil, flying in all directions in tiny droplets, vaporizes, and you then have a small fuel air bomb. Great if you want to be hairless, but otherwise a bad bad thing, especially indoors. See above about burn units.

Baking soda floats on the oil making a film that stops it from reacting with oxygen, and stops the fire fast. It works for most fires if you have enough to smother it.

The self sorting droplets at :50 are impressive.

It worked to give a visible aerosol, I'm just thinking it makes more than you would normally create, which I'm sure was intentional. You have to have more so you can see it if you don't have a Schlieren setup. That's what I want to see, in slow motion and HD so you can see the droplets along with the air currents. Then I'll have to design a negative pressure toilet or I'll never feel like using the bathroom again!

It reminds me of a good lesson I learned with fish. It's a good idea to not learn too much about something you use habitually, it can cause real problems! Sometimes it's better to just not know. ;-)

Comment hidden because you are ignoring dag. (show it anyway)

Wow, pretty Scifi stuff. I didn't think a screenless display would be possible without fog or droplets or something. Neat. Don't see how they could ever do colour though.

No, because rain is random water droplets. You need a body of water concentrated near the key fob.

Hopin' that oritteropo doesn't mind and apologies for posting the recipie contestants intentions submitted to my profile before I do it now, so I am asking here of user orriteropo if he'd like to have me post his entry here, in the public purview, since it was after all, submitted and has been approved as number 3...? Sounds like a tasty treat fit for the running so far, my oven marks go to 6 so I'd guess I can get it to happen close, I would like a name for these droplets of baked wonderfulness though...,make one up f ya have to or ask-about??-

Next I expect them to release a version of Wipeout XL where the cars hover on leidenfrost droplets.

3 more comments have been lost in the ether at this killed duplicate.

it's an example of the stroboscopic effect -- an optical illusion whereby the stream of water is vibrating at the same frequency as the video is running (presumably 24 fps), making it seem like the water is "streaming" in a spiral, when it's only those droplets captured by the video that are vibrating with the sound to make it appear that way. It's the same reason car wheels and propellers appear to change direction as they speed up or slow down when seen on film or through a strobe light.

Still, knowing how it works doesn't make it any less cool!

Needs Better lighting - Can't see a dammed thing!

Edit: Actually yes, My monitor is great. And yes, I understand that the darkened image is part of the high speed process. But they know that as well, and I just figured that photographing something so particular as tiny water droplets, they could have tried using either solid white or solid black backgrounds and better lighting to accentuate the bubbles and the popping.

If they are going to make a video with all the equipment, then set your space up properly. These guys do slo-mo all the time. I just felt they could take the time to do it right.

What a fing ordeal, squirt out 1/6th of that bag and go to work washing yourself, juggling tenths of droplets all over

Surprised the escaped water droplets and the little clip floating off don't cause problems. I bet he is more careful usually.

Wait, so there's absolutely zero water droplets left clinging to the side of the empty bottle or pooled at the bottom?
I call Shenanigans!

I imagine it's a result of various forces and circumstances (I don't think it's a coincidence that the droplets were soapy water which would increase it's surface tension/bubble strength).

Also keep in mind that a droplets surface would be a mesh of the outermost water molecules held together by their polar attraction. As the sphere bounces and moves its surface would have mini waves and ripples along it that would push against and then move away from the molecules on the water surface below it as the kinetic and polar forces acted.

If you imagine that every sphere of water had portions of its surface moving away from the water surface below and then oscillating back towards the surface while the molecules on the spheres surface that had been touching the water surface below would begin to oscillate back into the sphere.

This would create many points of contact oscillating against and away from the water surface below and thus there might not be enough contact/pressure between the 2 surfaces for it to coalesce at any given time. Imagine bugs whose feet are tiny enough for them to "stand" on water due to surface tension and the principle would be the same. It'd be like an infinite number of these bugs legs jumping up and down on the water at a microscopic level.

Also I'm not familiar enough with how water molecules align themselves while at the surface of something so perhaps the alignment of their atoms helps as well?

Thats all a guess though I'm sure you could google the real answer.

My guess is that in order for the two bodies of water (the main body and each droplet) to coalesce, their molecules have to agree on a resonating frequency. When there is no other interference, the droplets take on the frequency of the larger body almost immediately. Since the main body is resonating at a frequency above normal, the droplets can't "catch up", and so bounce and wobble along, trying to achieve equilibrium with the larger body, and failing.

Just a guess.
