The Rainbow Fish




Introduction: The Rainbow Fish

About: Just a guy in germany.

A long way out in the deep blue sea there lived a fish.

Not just an ordinary fish, but the most beautiful fish in the entire ocean. His scales were every shade of blue and green and purple, with sparkling silver scales among them. The other fish were amazed at his beauty. The called him Rainbow Fish. “Come on, Rainbow Fish,” they would call. “Come and play with us!” But the Rainbow Fish would just glide past, proud and silent, letting his scales shimmer. One day, a little blue fish followed after him. “Rainbow Fish,” he called, “wait for me! Please give me one of you shiny scales. They are so wonderful, and you have so many.” “You want me to give you one of special scales? Who do you think you are?” cried the Rainbow Fish. “Get away from me!” Shocked, the little blue fish swam away. He was so upset; he told all his friends what had happened. From then on, no one would have anything to do with the Rainbow Fish. They turned away when he swam by. What good were the dazzling, shimmering scales with no one to admire them? Now he was the loneliest fish in the entire ocean. One day he poured out his troubles to the starfish. “I really am beautiful. Why doesn’t anybody like me?” “I can’t answer that for you,” said the starfish. “But if you go beyond the coral reef to a deep cave you will find the wise octopus. Maybe she can help you.” The Rainbow Fish found the cave. It was very dark inside and he couldn’t see anything. Then suddenly two eyes caught him in their glare and the octopus emerged from the darkness. “I have been waiting for you,” said the octopus with a deep voice. “The waves have told me your story. This is my advice. Give a glittering scale to each of the other fish. You will no longer be the most beautiful fish in the sea, but you will discover how to be happy.” “I can’t…” the Rainbow Fish started to say, but the octopus had already disappeared into a dark cloud of ink. Give away my scales? My beautiful shining scales? Never. How could I ever be happy without them? Suddenly he felt the light touch of a fin. The little blue fish was back! “Rainbow Fish, please, don’t be angry. I just want one little scale.” The Rainbow Fish wavered. Only one very very small shimmery scale, he thought. Well maybe I wouldn’t miss just one. Carefully the Rainbow Fish pulled out the smallest scale and gave it to the little fish. “Thank you! Thank you very much!” The little blue fish bubbled playfully, as he tucked the shiny scale in among his blue ones. A rather peculiar feeling came over the Rainbow Fish. For a long time he watched the little blue fish swim back and forth with his new scale glittering in the water. The little blue fish whizzed through the ocean with his scale flashing, so it didn’t take long before the Rainbow Fish was surrounded by the other fish. Everyone wanted a glittering scale. The Rainbow Fish shared his scales left and right. And the more he gave away, the more delighted he became. When the water around him filled with glimmering scales, he at last felt at home among the other fish. Finally the Rainbow Fish had only one shining scale left. His most prized possessions had been given away, yet he was very happy. “Come on Rainbow Fish,” they called. “Come and play with us!” “Here I come,

Step 1: Collect Them All !

You have to collect a lot of different CD's, DVD's, Bluerays, LaserDiscs, and, so, on....
The best way to collect CD's is to post it in social network groups. Ensure the people that it is for art (Tell them they can put scratches on the CD's so that they can be sure that you wont collect their data. You can also ask small shops or small IT-Companys (The big one's are afraid of privacy violation's ఠ ͟ಠ )

Step 2: Get a MDF Panel.

You need a MDF Panel (medium-density fiberboard) from a Bauhaus like Home Depot, from a carpentry or maybe you'll finde a good board in the bulk garbage. The sizes should be like this:

23 feet x 27 feet x min 0.315 inch / 1 meter x 2 meter x min 0.8 centimeter.

Step 3: Get at Least 2 - 3 Hasp's & Enough Bolts and Nuts.

You need at least 2 - 3 hasp that can hold the weight and enough bolts with nuts to hold the hasp's. The bolts should be min 0,393 inch / min 1 centimeter long.

Step 4: Get a Lot Transparent Silicone Caulk / Silicone Adhesive

Get a lot transparent silicone caulk (500ml - 1000ml / 16 ounce - 33 ounce).

When the fish is going to be big and you want to get sure that the cds will stay glued, then you need a lot Silicone.

Step 5: Draw the Size & Shape

Draw the size & shape on a piece of paper and later on the panel. If you don't have such awesome and great drawing skills as i, you should draw it with a pencil.

Step 6: Trim the Panel With a Saw / Jig Saw

Trim the panel with a saw or a jig saw. It doesn't has to be perfect, because the CD's will be protrude beyonde the panel and cover it. Be aware of the tail, the fins and the hasps. The hasps should not protrude beyonde the panel. That's why you should saw into the panel (-> See the picture). Put one hasp on the prefered location and mark the square with a pencil. You should also mark the holes of the hasp to drill in later.

Step 7: Drill the Holes & Screw in the Hasp's

Drill holes in the marked circles for the hasp's. Be careful that you screw in the hasp on the correct side. They should not protrude above the board. That's why you had to saw into the panel.

Step 8: Cut CD's for the Fin's and the Tail

Cut CD's for the fins and the tail. Be slow and careful, some CD types start to crumble or burst.

Step 9: Glue, Glue, Glue.

Arrange the CD's and CD Parts (for the tail & the fins) as you like and glue them on with the transparent silicone adhesive. Its easier when you begin with the tail and work towards the body. When you reach the fins, glue them first on the panel. Glue the CD's from the outside (the edge of the panel) to the inside. The CD's should cover the hole panel, that means that the CD's on the edge should be protrude beyonde the panel and cover it.

Step 10: Tadaa...

After waiting till the glue is dry (i guess that took 8 hours but wait 3 weeks to be sure....), you can hang the Fish on the wall with a rope through the hasp's. For my second fish on the first picture, i used a transparent thin but strong nylonrope. And for my first fish i made on the third picture, i used a normal white hemp rope.

I apologize for my bad english and wish you a lot of fun with tinkering. :)

    Interesting idea and a nice effect. I like it.

    Did you use a silicone caulk or an actual glue? I am curious how well it holds together because it can be hard to get things to stick to CD's. Also with that much silicone it must have taken a while for it to cure and lose the smell. A smell I know well, as I use a lot of caulk and it can get a little overpowering. I imagine you had to keep the windows open when you were assembling it.

    Does it make an interesting reflection when the sun shines on it?

    I also like the 2 different patterns that you have. Have you tried others?

    Glad you like it :)

    You are right, its silicone caulk, the stuff you use in the kitchen and in the bathroom, right? In germany its called "Silikon Kleber" and kleber means glue ^^.
    It sticks perfect, i was very surprised. The CDs are more likely to break, than to get off the panel.

    Yeah, the smell is going to stay for maybe 1 till max 2 days, but its okay ^^ My nose is anyway not that good.

    The reflections at daylight are beautiful. That's why the first fish hangs in a wintergarden. I tried other patterns but i didn't make any pictures and gave the projects away. As a gift to good friends of mine.

    You are inspiring me --- I just a had a few other ideas.

    First, what would you think about using a hole saw with a drill press to cut out smaller circles so you could make smaller fish. And what about trying some other things like humming birds, which are very colorful?

    This would be awesome in the kids room in the library!

    I paid a library in my town a visit and wrote them a mail. They never responded.
