Water forms floating 'bridge' when exposed to high voltage - Physorg

"When exposed to a high-voltage electric field, water in two beakers climbs out of the beakers and crosses empty space to meet, forming the water bridge. The liquid bridge, hovering in space, appears to the human eye to defy gravity."



Now, does anybody thing that was a Russian water tentacle?

Super cooled water.

I never get bored of seeing this experiment.

You have me imagining new kinds of sea monsters, sir... :o

I thought this video, linkes from the above supercooling one, was delightfully steampunk.
Not poems and rubbish - SCIENCE!

Oh and here I thought it was just something that occurred when one took a can of soda from a very cold cooler. Liquid until you pop the top, then gushing slush.

No, the cola thing is just because the CO2 pressure above the liquid decreases as you open the can. There is no phase change involved.
Apparently though, ketchup is solid untill you give it a smack, then it turns liquid. Hence why those Heinz bottles end up drowning your spaghetti.

Ahh, thanks for the info. Guess who wasn't paying attention in science class?

And ketchup. On your spaghetti?

Very similar effect was described at least as far back as 2005, pictures at http://tesladownunder.com/HighVoltage.htm#Strange%20HV/water%20effects
