Challenge to the nature of stinginess or bee, "NIGHT RAINBOW PROJECT" to rain a night in Roppongi

Although it is "rainbow" which can hardly be seen in everyday life, the country that the rainbow often takes · New Zealand airline "New Zealand Airlines"Rainbow over the night skyTry not to try "NIGHT RAINBOW PROJECT"In Japan

"To put a rainbow in the night sky" seems to be a great challenge to nature, but in execution it is a matter of intention to take all the troubles such as ordering equipment from Japan that could not be procured in Japan It was.

A beautiful nurse CA (cabin attendant) named Daniel Rainbow who is working at New Zealand Airlines has appeared and the event was progressing lively while children of general participation gathered, but wonderfully watching the rainbow to the night sky Was it possible to put it on?

Making landscape of the rainbow and the appearance of the production are from the following.Let's go see the color you have never seen before

Arrived on site.


In the immediate vicinity of Tokyo Midtown,21_21 DESIGN SIGHTIt was held in the park right next to.


First of all, there are two huge cranes that jump into our eyes and the cables passed to it. They have installed a pipe for spraying fog.


It seems that a rainbow is made at 18:30.


In the first place rainbow is a colorless transparent (white) light of the sun entering water grain, the way each bend (refraction index) differs in grain depending on the color contained, so that each color seems separated. It seems that a rainbow is formed by the fact that the light finally reached from our grain and reaching our eyes is red or yellow, respectively.

In addition, how to put a rainbow on the night when the sun does not appear is how to use the structure of nature as it is, adjusted the angle so that the light of the separated color towards the eyes of the people on the ground reaches The artificially generated artificial sun "to irradiate the mist to create a rainbow.

And, the artificial sun used in this project is riding on the tip of the crane.


Immediately behind it, the water spray is on standby.


These are sprayer which plays a role of blowing fog according to wind direction. It is for raising fog from another angle from the spraying tube passed by the crane.



Projector for projecting New Zealand Airlines logo etc. during the event. Facilities such as artificial sun are too huge so it looks somewhat hazy, but this is too big enough compared with what is used in ordinary events etc.


As I was about to hunt inside the hall, the days gradually began to tilt.


A crane carrying an artificial sun rose. I did not understand it because it was collapsed earlier, but it is a great height.


It was said that general participants could participate in making rainbow, and a lot of people gathered at the reception.


Participants write a consent form here. Even if your face is reflected on TV cameras etc which are primarily covered by coverage, it is such contents.


A rainbow color candy named after the rainbow was also prepared.


People who participate in making rainbow will sprinkle water from below with a sprayer on hand so we will lend you a raincoat so that it will not get wet. One scene that CA will dress for children.


The staff wearing matching matching T - shirts are busily moving around.


The spray test started.


The artificial sun also starts to light up.


It got dark in the morning, and the test was continued in the meantime. At this point I can not see the rainbow yet.


The moment of destiny approaches, the general participants stand by as if they can be called the stage sleeves.


While I was doing this, the test continued and the condition was set up or a rainbow appeared in the sky. Although it is not a semicircular one, the fog certainly has a rainbow-colored fog.


As a result of trying to blow mist from the bottom with a sprayer, the rainbow is scratched. It seems easy to be influenced greatly by the wind direction, it requires a lot of extensive facilities but fine adjustment is required, it seems to be very difficult.


Still it was possible to create a rainbow-colored band, and the test ended in a reasonable result.



And it became 18:30, the event began. From here it is a real game. By the way, attendant reflected in the center is Daniel Rainbow, a beautiful woman who got out of project leader because it is a name that is too perfect for this project. "Rainbow" is a real name, and it was said that it appeared by chance on a new in-flight safety video made after the project was launched, so it became obvious.


The general participant "Team Rainbow" is also ready.


The Edo Albury Japan branch manager has also appeared, and the countdown is about to begin.


After the countdown with the voice, the artificial sun was irradiated. It is a bit confusing, but in the second half of the movie there is a flickering rainbow.



A picture that captured the rainbow that occurred is like this. A voice saying "It looks like Aurora if anything" was also heard.



The rainbow will change its shape immediately even if the wind direction and how the mist is blown up slightly change.



I will approach the site spraying fog. Since I've been keeping fog all the time since testing, the ground is pretty bishochi.


With this kind of feeling, each person grips the nozzle and fires it toward the person who likes the fog.


Especially at this time a big cheering came up, such as people who are doing Banzai, but it was because it seemed that the rainbow just took it round on top when seen from the person who had the nozzle. I wanted to do it for a while, but I abandoned with various circumstances such as having a camera.


At the end we took a memorial photo and the event closed the curtain.



After that, for a while, general participants took time to make a rainbow freely, old men and women who are still not enough to play were hungry.


The tension seemed to be pretty high before it began as being an adventurous attempt to put a rainbow at night, but at the moment when a rainbow occurred, there was a great cheer from the audience and the mass communication seat. It seemed that the goal of "making people happy" and "delivering a rainbow of New Zealand" that was the object of the project was achieved.

The official report of the project has been uploaded to the following site, so it is interesting to see pictures of different scenes when checking here.
