While Astronaut Jim is cleaning the Rover and TV camera, Joe at Houston makes a Joke, asking Astronaut Jim to clean the 'Lamp' Light Source that is pretending to be the Sun. Jim says Jokingly to turn the camera upwards so Houston can watch him clean the Large Lamp Light that is high up in the Ceiling of the Fake Moon-Set Studio Bay. Joe at Houston says at :03 "And could you dust our Lamp while your there please."(Astronaut Dave is heard laughing) Astronaut Jim says at :09 "Yep, stand by". Astronaut Jim says at :23 "Your cleaned up, thew." Joe at Houston says at :27 "Clean the top of the camera first please". Jim replies "Ah ok". Joe at Houston replies "Ah thats beautiful, oh magnificent, that even made us blush down here." Astronaut Jim says at :47 "Ok the tops clean, if you'll point up a little bit I'll ah,.......Clean your Lamp." Joe at Houston says at 1:17 "Could you check the oil too please".(As Astronaut Jim walks away laughing) This video as you hear it, is located for download at NASA site: ******* Apollo 15 Video Library Working below the Rover in the Station 6 crater.

Inside every plant cell, a cytoskeleton provides an interior scaffolding to direct construction of the cell’s walls, and thus the growth of the organism as a whole. Environmental and hormonal signals that modulate cell growth cause reorganization of this scaffolding. New research led by Carnegie’s David Ehrhardt provides surprising evidence as to how this reorganization process works, with important evidence as to how the direction of a light source influences a plant’s growth pattern.

This "V8-Engine" has semi-realistic exterior and interior detail. It is made entirely from paper (except a motor, a battery holder, a few plastic tubes and electrical wires). No paint applied. It looks pure and elegant. Various shadows created by different light sources make the appearance more 3D.

Here's a typical example of a supposed 'UFO landing in the woods'. Its very similar to the GUARDIAN footage. Just because the two left light sources light up the woods and there's a blinking indiscriminate light, there is no reason to suggest that this is an 'outworldy' spacecraft. You wanna know what it really is? Two epicenters of a forest fire up in Dionysus mountain in Athens and a truck from the local F.D.!

Mysterious Ball Lightning Created in the Lab By Ker Than LiveScience Staff Writer posted: 23 February 2006 08:56 am ET Ball lightning is one of the most mysterious phenomena in nature. Now scientists have created a laboratory version of the eerie floating orbs using technology taken from a common microwave oven. The work could help scientists figure out how the lightning forms in nature and lead to practical applications that harness its power. In the wild, the little bundles of energy are typically only a few centimeters across, although some have been reported to be the size of beach balls or larger. They are closely associated with regular lightning and thunderstorms and have been seen in many different colors. Witnesses report hissing sounds and an acrid ozone odor when the lightning balls appear. The vivid apparitions normally hover or float around for only a few seconds before vanishing suddenly, either silently or with an explosive bang. Although people have known about ball lightning for centuries, scientists have yet to come up with an explanation that accounts for all of the strange properties. Microwave drill Eli Jerby and Vladimir Dikhtyar from the University of Tel Aviv in Israel created a laboratory version of ball lightning using a "microwave drill." The device consists of a 600-watt magnetron taken from a domestic microwave oven and uses a powerful microwave beam to bore through solid objects. The researchers aimed the beam through a pointed rod and into a solid object made from glass, silicon and other materials. The energy from the drill created a molten hot spot in the solid object; when the drill was pulled away, it dragged some of the superheated material along with it, creating a fire column [video] that then collapsed into a bright fireball that floated and bounced [video] across the ceiling of the metal enclosure. "The fireball [looked] like a hot jellyfish, quivering and buoyant in the air," Jerby said. The glowing object measured just slightly over an inch across and lasted only about 10 milliseconds. The work was detailed earlier this month in the journal Physical Review Letters. Glowing fluff balls The composition of the laboratory lightning ball still needs to be verified, but it appeared to resemble those found in nature. "Our experiment confirms to some extent the theory that ball lightning originates from hot spots in the ground created by normal lightning," Jerby told LiveScience. According to one popular theory, ball lightning forms when lightning strikes the ground and vaporizes mineral grains in the soil. The vaporized nanoparticles could then link together into chains and form a fluffy ball of silicon that floats on the wind. The particles react with oxygen in the air and release light as they burn. Jerby thinks that his laboratory lightning balls could one day find practical uses in industry. "My imagination leads me to speculate on applications like 'bulb-less' light sources, coating and deposition or energy production," he said.

The ball bearings in this video clip spin so fast it's unreal, and are even more entertaining when a light source is shone onto them.

About HADES: Horror, obscurity, identity, consternation from madness, transgression of the mind, multiplicity, censorship of the self...mind states that we tend to avoid, fear of darkness, fear of the depth, fear of ourselves... Hades is an attempt to naturalize the meeting of the individual in a conscious condition with those inner states of difficult acceptance or access, incomprehension and not obvious states that mind itself creates. Whereas our mind feeds us with images, our consciousness allows us to establish different levels of connection with our inner reality. Our capacity to extrapolate thought, to observe that reality and undertake it, that make us able to annihilate the negative connotations of any mood and be able to freely move in its natural state. Through the control of sound with motion-tracking sensors and by means of body movement, the performer represents an element of consciousness that naturally moves and copes with a series of hypnotic, gloomy and chaotic atmospheres charged with icy calm as much as with emotional intensity. Digital manipulation and projection of light sources, use of digital error and signal feedback, cuadraphonic sound and realtime production, these are the basis to generate an aesthetic language evoking those landscapes of mental darkness we are all familiar with.

Cool for Party Animals! Self Illuminating Hair and Body Gel for Mardi Gras - Spring Break - Party Time .- St Patrick's Day - Summer Festivals - Clubs - Raves -Beach parties This has got to be the The Coolest Hair and Body gel on the planet! The photo you see here, was taken in TOTAL Darkness. The design took me approximately 20 minutes to apply the to my skin and hair using iGlow. I used 4 colors as I wanted to try and blend them into each other to see just what kind of unusual multi glowing effect I could create ad lib. The gel was easy to apply, and I found it fascinating to use!. This somewhat clumsy "artistic endeavour"was created from someone (yours truly) who has absoloutly no painting/drawing skills as such!. If a Klutz like me can do it, what ,I wonder, could the more artisticly inclined achieve? The weird thing is, you start out in total darkness, (in front of a mirror), and as you fire up iGlow, and mix,(3 minutes) the room suddently starts to become eerily discernable as the product actually starts the process of creating its own bright light source (as quick as 20 seconds... Enough to see by ...From thence forth, its merely a case of tracing out your intended pattern with the gel, and hey got glow!. You are in essence, "painting with light. Now, for the uninitiated, "iGlow" Self Illuminating Gel is the newly improved version of the wildly popular "Voltage" Hair Gel, now discontinued, and usurped by this brash new contender to the throne of light.. The difference is: iGlow glows (amazingly so), TWICE AS BRIGHTLY as the original Voltage gel, and now FIRES UP IN SECONDS instead of having to wait several minutes for the color to activate. A patented process takes ordinary hair color and makes it extraordinary, by adding self-illuminating glow. iGlow does not rely on UV, neon or black lights to create glow. Instead, it produces its own light. Tiny, microscopic particles in the gel come together in the mixing process to produce a bright colorful glow that can be seen in partial light and in the dark for at least 4-6 hours. A true Glow in the dark product. Eco friendly. No animal testing was used in hte manufacture of this item which is another plus factor about the product. The best thing is, while iGlow is classified as a "temporary hair color" it does not actually color the hair cuticle. Rather, It "coats" the hair with color. The gel is the delivery medium for the luminescence (glow). This means it is safe for color-treated or bleached hair when used as directed. The gel has an added "day tint" which will show up on the hair/Skin under normal lighting conditions. When lighting is reduced to about half-light - After sunet or indeed in Total Darkness as in the photo ( Indoors or out) all colors emit a stunning vibrant glow.. The iGlow Gel's effect is activated when you first open the container and mix the contents as instructed using the provided applicator. Once activated, the glow will last for at least 4-6 hours. Each container is intended for one-time application but depending on the effect desired and amount of gel used, one container is typically enough for two people as a little "dab" will go a long way. Create streaks or spikes of bright glowing color, or go all out with a full Glow effect. Usage hint: Blow-drying hair for 15 -20 seconds, will increase the intensity of the brightness but shorten the duration of the glow. iGlow is meant for short-term use only and should be washed out of the hair before going to bed. To remove iGlow simply shampoo out. iGlow is safe and non-toxic,(*FDA and EU safety approved for use on the hair and skin) but is not recommended for young children 8 years or under without supervision. Glows in the dark...without UV, neon or black lights. Lights up in seconds. Glows twice as brightly as Voltage Hair Gel Hair glows brightly for Hours (lasts for 4-6 hours)! Comes in 9 great colors. Washes off easily with shampoo. Main advantages of this unique Chemiluminescent glow product: Safe and fully tested for safe use on the hair and skin. Will Glow indoors or out without any other light source. No UV, Neon or recharging of any kind required. Use for Raves, Nightclubs, Music festivals, Halloween, Xmas and New Year, Celebrations, Parties, Spring Break, Mardi Gras, Carnivals, Fundraising, Sports events, special fx in movies etc... Check out more info on iGlow at the offical USA Site: www.voltagehairgel**** See these amazing online videos to watch the process in action: www.metacafe****/watch/706223/ (The mixing process in all 9 colors, and shots of the product in Total darkness.

Take a look at the videos...IGLOW: its weird, its fun, its cool!.

In physics, a laser is a device that emits light through a specific mechanism for which the term laser is an acronym: Light Amplification by Stimulated Emission of Radiation. This is a combined quantum-mechanical and thermodynamical process discussed in more detail below. As a light source, a laser can have various properties, depending on the purpose for which it is designed and calibrated. A typical laser emits light in a narrow, low-divergence beam and with a well-defined wavelength (corresponding to a particular color if the laser is operating in the visible spectrum). This is in contrast to a light source such as the incandescent light bulb, which emits into a large solid angle and over a wide spectrum of wavelength. These properties can be summarized in the term coherence.
