Water forms floating 'bridge' when exposed to high voltage

And while we're on the small stuff:

Fill a glass with water until the water presents a positive minuscus, i.e., the water surface is higher than the rim of the glass. Charge up the comb by briskly combing your hair. (You can verify that the humidity is not too high by picking up small pieces of paper with the charged comb. If the paper won't jump to the comb, wait until drier conditions occur.) Bring one end of the charged comb, teeth down, toward the water surface while watching the surface at eye level. When the comb is about two centimeters from the water, a "micro-mountain" of water will begin to rise toward the comb. The closer the comb comes to the water surface, the higher the micro-mountain. As you continue getting the comb closer, a point will be reached where a spark will jump between the mountain and the comb. (If you have normal hearing you'll be able to hear the audible "crick" of the spark.) Immediately after the spark jumps, the micro mountain will collapse and produce a circular "tidal wave" which will rush away from the spark site.

Never happens in nature though. /sarc

Never.

Like, *PING*, dudes.

Pretty neat demonstration

So, this is why you get waves in a storm, they are trying essentially to leap into the sky, find lightning. When the waves realize they are a failure, they rush to shore, crash themselves in kind of a humility ritual? Or am I reading into this comb thing too much?

Elmar Fuchs? Good golly, worst name of all time? Though I did have an account with Richard Glasscock one time, not kidding. I never tried calling him Dick...

I don't believe AVLBs and Bailey Bridges are going away time soon.

Those waves had nothing to apologize for huh!?

Mission, accomplished sir!

Hey, this is cool. Here in WA State, I follow weather satelite pics. I do this to see if I can golf or not...

Anyways, the storms that come through here, some appear to be like swirling hurricanes just off the coast of the pacific, heading up, towards alaska. When they get close enough, then we get mass wind. Last year was unreal, like a hurricane, damage spectacular.

ELECTRIC WEATHER

>>The oxygen (blue) side of the water molecule is more negative than the hydrogen side (red), forming an electric dipole.

In an electric field, the water molecule will rotate to line up with the field. When it condenses in a cloud the average electric dipole moment of a water molecule in a raindrop is 40 percent greater than that of a single water vapor molecule. This enhancement results from the large polarization caused by the electric field induced by surrounding water molecules. In the atmospheric electric field the water molecules will be aligned with their dipoles pointing vertically and in a sense that is determined by the charge polarization in the cloud. It is interesting to note that the tops of storm clouds are positively charged and the base is negative. That is the reverse of the radial charge polarization within the Earth itself. And it is this charge polarization that gives rise to the low-order attractive force we call gravity. So it is proposed that water droplets in clouds experience an antigravity effect. It appears to be related to the 'Biefield-Brown Effect,' where a charged high-voltage planar capacitor tends to move in the direction of the positive electrode. That effect may explain how millions of tons of water can be suspended kilometres above the ground, when cloud droplets are about 1,000 times denser than the surrounding air...

The boom of thunder and crackle of lightning generally mean one thing: a storm is coming. Curiously, though, the biggest storms of all, hurricanes, are notoriously lacking in lightning. Hurricanes blow, they rain, they flood, but seldom do they crackle.

Surprise: During the record-setting hurricane season of 2005 three of the most powerful storms--Rita, Katrina, and Emily--did have lightning, lots of it. And researchers would like to know why.

Hmmmmm, thanks for the link...

fyi

And some people who have survived the experience of being "run over" by a tornado have reported an electrical glow in the inner wall of the tornado.

I knew a woman in the 70's whose sister or friend or some such person, had seen the inside of a tornado from a crack in a strong cellar trap door. I didn't pay much attention to the story because what she saw seemed so improbable -- that the inside of the tornado had little lightning bolts through-out it. Now, I wished I had asked a few questions... Thanks for the link.

I have also heard similar stories. Here’s one:

...At last the great shaggy end of the funnel hung directly overhead. Everything was as still as death. There was a strong gassy odor and it seemed that I could not breathe. There was a screaming, hissing sound coming directly from the end of the funnel. I looked up and to my astonishment I saw right up into the heart of the tornado. There was a circular opening in the center of the funnel, about 50 or 100 feet in diameter, and extending straight upward for a distance of at least one half mile, as best I could judge under the circumstances. The walls of this opening were of rotating clouds and the whole was made brilliantly visible by constant flashes of lightning which zigzagged from side to side...
