Water bridge created with high voltage


Physicist Elmar Fuchs and his colleagues from Graz University of Technology are investigating why water, when exposed to high voltages, forms this strange liquid bridge as the liquid moves from one beaker to another. They published their research in the Jouranl of Physics D: Applied Physics. The water bridge was cylindrical with a diameter of 1 to 3 mm and spanned as much as 25 mm. From PhysOrg.com:

Initially, the bridge forms due to electrostatic charges on the surface of the water. The electric field then concentrates inside the water, arranging the water molecules to form a highly ordered microstructure. This microstructure remains stable, keeping the bridge intact.

Firefox: Run Faster Without Rebooting Reinstalling

firefox_logo.png If Firefox has a flaw to get bummed about, it's that it slows down your machine after a few hours of steady computing. Digital Inspiration has a workaround for this that (yay!) does not include any sort of restart reinstalling:

  • Start Firefox and export your bookmarks as a file on your hard-drive (we'll need them later).
  • Type firefox.exe - P in the Run box of Windows.
  • Click the Create Profile button without making any modifications to your existing profile (which is normally called "default")
That should do it; now, when you start Firefox in your new profile, you should be up to speed (get it?). Sure, it won't have all the tweaks of your old profile, but if you're just looking for a CPU break, this might be the way to go. Note: Be sure to check out Gina's post on managing multiple Firefox profiles for further info.

Image Editing: Resize Images without Sacrificing Content with GIMP or Rsizr

Popout Ever have to crop or resize a picture to fit it better on a web site but end up disappointed with the content you have to lose from the photo? Using a method called liquid rescaling, your pics can be rescaled while retaining almost all of the pertinent content, so you can get the best of both worlds—a smaller image that retains everything you want. If it still sounds a little unclear, check out the video to see this brilliant idea in action.

If you're a fan of the open source image editor GIMP, you can download and install the Liquid Rescale GIMP plug-in to get liquid rescaling results (after you install it by moving the downloaded files into your GIMP directory, you'll see the Liquid Rescale option under the Layer menu). If you don't feel like installing anything, you should try out the Rsizr webapp, which does the rescaling from the comfort of your browser. Both tools are a good deal slower than what you see in the very cool video above, and neither are implemented to the full extent of what you're seeing in the video, but the results are still promising.

Clocks: CB2's World Panel Clock is Sci-Fi Sexy

cb2_lcd_clockgi.jpgOur desks are so cluttered we have given up the fight for organization, and that is exactly why we are tempted by CB2's World Panel Clock.

The timepiece is battery powered, which will saves you adding to your wired disorganization and is available for a reasonable $24.95.

Mansion: Jelly-fish 45 Habitat Won't Sting Your Pocket Too Much

thejfish.jpgIf you have fallen a little short of the $50 million price tag for a Poseidon 180, fret not, the Jelly-fish 45 Habitat will set you back only a mere $2.5 million. Bargain! Designed by Giancarlo Zema, the "floating dwelling" comprises five separate levels all connected by a snazzy spiral staircase.

jellyfishInteriorgi.jpgThe floors are split into cheesy zone-titled areas including study, night, day, guest and viewing quarters. Though, if you purchase the floating mansion, you may abide by whichever nomenclature you wish. The viewpoint stretches 3m below the surface and looks jellyfish-like fantastic. The colossal seat-in-the-sea stands 10m high and 15m wide. Now, if I manage to roll out one hundred posts in 24 hours, Blam promises me a tour of his Jelly-fish 45 Habitat—game on!
