What is a Lumia Box?\nA lumia box is also known as a "camera obscura". The words camera obscura mean "dark room" in Latin. Some camera obscuras are really the size of a room; you actually get inside, and look at images on the wall coming from either a hole or a lens on the opposite side of the room.\nI call this project a lumia box because the purpose is not simply to look at images of the world, but to create unusual images of pure light. "Lumia" historically are kinetic-art sculptures that create patterns of moving, vibrant color. This simple box makes that possible.\n\n\nMAKE A LUMIA BOX\nA cardboard box and some tissue paper make up the lumia box. A box that is fairly short and wide is best. The ideal dimensions are 9 by 9 by 4 inches, but you can vary these according to what you have available. The kind of box that has a slip-on lid is preferred, but this, too is only an ideal. Basically, you want one end of the box to have a cutout in it over which you will place apertures, and the other end you will fit with a tissue paper screen. You will also need:\nSeveral pieces of aluminum foil that you can cut apertures of various shapes into;\nA box cutter knife;\nAn X-acto knife or scissors;\nBlack construction paper or aluminum foil;\nMasking tape.\n\nAssembly of the lumia box is straightforward. Remove the flaps if you are using the kind of box that closes with flaps. Close the flaps on the other end of the box and seal with tape. Cut an opening about two inches square into the center of the closed end of the box. \n\nNow you have a box that is completely open at one end, and has a two-inch square aperture at the other end. Tape the tissue paper over the open end of the box. Now your lumia box is ready to accept apertures. \nNow you have a box that is completely open at one end, and has a two-inch square aperture at the other end. Tape the tissue paper over the open end of the box. Now your lumia box is ready to accept apertures.Using a sharp knife, such as an X-acto knife, cut patterns into pieces of foil. Try to keep the features small. If this is beyond your skill, try using thin black construction paper for your apertures. Then you can use scissors to cut openings into them. Some suggested shapes are shown below. \n\nInstall one of the apertures onto the lumia box. Hold the box with the screen toward you and point it at a point light source. You should see the aperture projected onto the screen. If you have access to a string of Christmas tree lights, or a tree that is decorated with these lights, try looking at the lights with your lumia box. Bring the box right up to the lights for the best 3-D effect.

the enzymes in glow worms is called luciferase. In cells, bioluminescent reactions occur between a protein known as a luciferin and oxygen, and are driven by an enzyme called a luciferase. The enzyme is the middleman whose job is to take raw luciferin "fuel" and react it with oxygen to make oxyluciferin, which then produces light.  In the first, the luciferin, when oxidised, produces a colour that is decided by the complex genetically determined nature of protein. In the second, the luciferin, the luciferase and the oxygen are all bundled up into a single photoprotein molecule. The energy that excites the light-giving electrons is transferred when the molecule is triggered by charged calcium atoms.\n\nSuch bioluminescence reactions are an example of the chemical elegance of living things, but they are also fascinating for another reason. Chemicals that produce something as harmless and as easily detectable as light within a cell could illuminate the inner workings of living things, given a little gentle tinkering. Genetic engineers have been doing just that.\n\nThey have isolated exactly how bioluminescent proteins produce a particular colour of light by examining the DNA that describes how to make the proteins. By altering this template, they are able to tailor-make their own light producing biomolecules.

Depends upon the product.  Some contain preservatives, some do not.\nSodium copper chlorophyllin derived from the alfalfa plant is relatively stable.  Some products add methylparaben and propylparaben (derived from benzoic acid) to preserve the product.  These solution have shelf lives of up to one year.\nExperiments with liquid chlorophyll solution show that even when they decompose (stored in heat and light), they form no toxic products.\nYour product may have an expiration date on it.  The solution should be useable for at least six months past that date.

These bacteria probably have the lux gene which codes for bioluminesence. A resonable mechanism that would cause this to arise is mutation. These lighted cells would probably have benefited some how from glowing in the dark. Some deep sea fishes have bacteria which code for this gene (Vibrio fischer) Which may have helped these fish find food in the dark waters. Thus those fishes without this gene would have died out because of natural selection. What you could do is put these fishes with the bacteria that glow in the dark in the same pool of dark water as the fishes without this gene. Then provide a limited food source so that not everyone could receive food and only the strongest would survive. If the fishes without this bacteria eventually died out but the others stayed alive, you have proven your hypothesis. If not, then failure willl be an obsticle to overcome.\n\nHope i was helpful

I have recently wondered the answer to this question myself.  I think that passive dyes, such as ROX, constantly emit a flourescent signal.  This signal is not supposed to be influenced by the PCR reaction cycle (ie "passive").  I believe the ROX dye is a rhodamine labeled amino acid, or maybe a short peptide. Other passive dyes are probably similar.

You are correct that the box is the color of the light it reflects.   Alternatively, you can say:  The box is the color not absorbed by the molecules on its surface.     But you would never say the box is the color absorbed by the molecules on its surface.   That is, your last statement is false.

So the answer to your specific question is 'no'.  The problem is that if the container shines, it means that light and energy is being lost and will eventually run out.  There are materials that will glow for a long time due to radioactive decay or via chemical processes, but all of these are using up their 'fuel' in the process and will eventually run out.\nSome radioactive substances have a pretty long half-life and will appear to glow steadily without much decay over the scale of a human lifetime.\nNow, to get more generalized... it is possible to trap light in a container that doesn't shine. Scientists have been able to free light in its place using supercooled clouds of sodium which are naturally opaque, but can temporarily transmit light when altered via a laser beam.  If the laser is shut off, a light beam that is passing through the cloud will be temporarily frozen in place.  Australian scientists have recently been able to extend this interaction to be nearly as long as a second.\nOnce the laser is reintroduced the beam is recovered and continues on its way.  Now all this is a little debatable, since the photons actually get temporarily swallowed up by the material.  The photons that come out afterwards have the same configuration and quantum state as what went in, but whether they are exactly the same photons is more of a question for philosophy than for physics.

One lux is equal to one lumen per square metre, where 4π lumens is the total luminous flux of a light source of one candela of luminous intensity.\n\nThe difference between the lux and the lumen is that the lux takes into account the area over which the luminous flux is spread. 1000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1000 lux. The same 1000 lumens, spread out over ten square metres, produces a dimmer illuminance of only 100 lux.\n\nAchieving an illuminance of 500 lux might be possible in a home kitchen with a single fluorescent light fixture with an output of 12000 lumens. To light a factory floor with dozens of times the area of the kitchen would require dozens of such fixtures. Thus, lighting a larger area to the same level of lux requires a greater number of lumens.\nlumens/sq ft      10.76             lumen/sq metre \nlumens/sq ft      10.76391       lux (lx) \n\n\n\nMore at the link below:

Each pixel is a small sealed chamber of gas that illuminates when ionized.  They're arranged on a grid of "wires".  When a particular X-Y junction is energized, that pixel lights up.  It happens thousands of times per second.
