10 THINGS THAT ARE GOOD - THINGS THAT GLOW IN THE DARK

After todays workshop on what is good, I have decided to look into things that glow in the dark. I will research into different areas of glow in the dark items, from naturally glowing things to man made items. 

Why glow in the dark stuff is good:

1. Looks nice

As glow in the dark stuff is out of the ordinary, it can be a very interesting media to work in. It seems to facinate most people. You are automatically drawn to it.

2. Hidden Art

Hidden Art: You can create multiple pictures in one using photo-luminiscent products. Theatrical props use this technique extensively so that they can change the mood or set without moving a prop. They simply change the lighting and the new scene appears. Artists use this to fascinate the viewer. Mural makers use it to create one vista during the day and then with a black light create a nightscape.

3. Kids love it

Decorate bedrooms, glow in the dark pictures and books etc are engaging for children.

Shadow Wall: Children's Museums around the world have shadow walls, which are a wall of our short glow paint used with a strobe light. When the light flashes, the shadow of the person in front of the wall will remain for about a minute. This process can be repeated an infinite amount of times.

4. Attracting mates

The attraction of mates is seen actively in fireflies, which use periodic flashing in their abdomens to attract mates in the mating season.

In the marine environment, use of luminescence for mate attraction is well documented only in ostracods, small shrimplike crustaceans. Pheromones may be used for long-distance communication, with bioluminescence used at close range to enable mates to "home in".

5. Distraction

Certain squid and small crustaceans use bioluminescent chemical mixtures or bioluminescent bacterial slurries in the same way as many squid use ink. A cloud of luminescent material is expelled, distracting or repelling a potential predator, while the squid or crustacean escapes to safety

6. Repulsion

Aposematism is a widely used function of bioluminescence. It is suggested that many firefly larvae glow to repel predators. Millipedes have been shown to glow for the same purpose

7. Communication

Communication between bacteria (quorum sensing) plays a role in the regulation of luminesence in many bacterial species. Using small extracellularly secreted molecules, they are able to adapt their behavior to turn on genes for light production only when they are at high cell densities.

8. Illumination / Catching Prey

While most marine bioluminescence is green to blue, the Black Dragonfish produces a red glow. This adaptation allows the fish to see red-pigmented prey, which are normally invisible in the deep ocean environment where red light has been filtered out by the water column

Angler FIsh

Angler fish glow in order to attract prey, creatures are attracted to the light

then they are snapped up at the last minute.

9. Wayfinding

Now a days there a many examples of glow in the dark signage used.

These signs help in times of distress, power cuts, fires etc. Very Helpful

10. Security

Invisible Markings: Marking items invisibly has a far-reaching effect. Mark your tools, important documents, car parts, returns, and just about anything. No one will know and they can only be seen with a black light.
