Incredible Fluid Motion Experiment
A fluorocarbon-based ferrofluid, with about 400-G saturation magnetization and low field magnetic susceptibility of 3, is placed within a glass Hele-Shaw cell of 1.1-mm gap. Magnetic fields are applied that have in-plane clockwise rotating and dc axial magnetic fields. The ferrofluid is surrounded by a 50/50 mixture of isopropyl alcohol and deionized water, which prevents ferrofluid wetting of the glass plates. In all cases, the rotational field strength is 20 G rms, and the frequency is 25 Hz. The dc magnetic field will be increased from 0 to 100 to 200 G.
The first experiment uses a 50-µl drop of ferrofluid. The dc axial field is first increased to 100 G, and then the clockwise rotating field is turned on. The ferrofluid drop is circular before the magnetic field is applied. When the dc magnetic field is applied, the ferrofluid drop forms a spiking labyrinth pattern. Then the clockwise rotating field is applied, and the spikes begin to curl in on themselves, forming a smooth spiral pattern after some of the spikes are absorbed into the larger structure. The smooth spirals form from viscous shear as the clockwise rotating magnetic field causes counterclockwise flow on the outside ferrofluid surfaces, which return on the inside surfaces.
The second experiment uses a 200-µl drop of ferrofluid. First, the clockwise rotating field is applied, which causes a counterclockwise flow that holds the circular fluid drop together without spikes. Then a 100-G dc axial field is gradually applied. This results in the ferrofluid drop appearing to expand before a phaselike transition at a critical dc magnetic field strength around 100 G. Careful observations show that the pattern forms at slightly less than 100-G dc field under a thin ferrofluid coating on the top glass plate, which then abruptly peels away at slightly increased dc axial magnetic field. The magnetic field is then increased from 100 to 200 G to form an intricate internal pattern surrounded by a circle of ferrofluid with spiraled arms. The second experiment is repeated again three more times under essentially identical conditions, with common features but it appears that the fine features are different each time.

NEW INCREDIBLE HULK TRAILER!
The new 2008 Incredible Hulk Trailer the hulk looks incredible enjoy the brand new trailer for the new 2008 film "The Incredible Hulk", starring Ed norton as Bruce banner / The Incredible Hulk Also starring, Liv Tyler as Betty Ross, Tim Roth as Emil Blonsky, William Hurt as Gen. Thaddeus 'Thunderbolt' Ross, Ty Burrell as Dr. Samson and even Robert Downey Jr. as Tony Stark in a cameo tying into Iron Man!
From IMDB;
Depicting the events after the Gamma Bomb. 'The Incredible Hulk' tells the story of Dr Bruce Banner, who seeks a cure to his unique condition, which causes him to turn into a giant green monster under emotional stress. Whilst on the run from military which seeks his capture, Banner comes close to a cure. But all is lost when a new creature emerges; The Abomination. Written by Graham Kroon
A cure is in reach for the world's most primal force of fury: THE INCREDIBLE HULK. We find scientist Bruce Banner, living in shadows, scouring the planet for an antidote. But the warmongers who dream of abusing his powers won't leave him alone, nor will his need to be with the only woman he has ever loved, Betty Ross. Upon returning to civilization, our brilliant doctor is ruthlessly pursued by The Abomination -- a nightmarish beast of pure adrenaline and aggression whose powers match The Hulk's own. A fight of comic-book proportions ensues as Banner must call upon the hero within to rescue New York City from total destruction. One scientist must make an agonizing final choice -- accept a peaceful life as Bruce Banner or the creature he could permanently become: THE INCREDIBLE HULK.
