A well-known natuÂral specÂtaÂcle is the rainÂbow, a very colorful striÂpe that is always curÂved when viewÂed from the earth. If the canÂton of NidÂwalÂden, seen from LucerÂne, comes into a “wash cycle” (heaÂvy rain), this specÂtaÂcle is frighÂtening for thoÂse “insiÂde” and a natuÂral specÂtaÂcle for thoÂse who look from the outside.
Why is theÂre a rainÂbow? Who puts the color in the rainÂbow? Why is the rainÂbow always bent? Who always arranÂges theÂse colors in the same order? Under what conÂdiÂtiÂons are the colors reverÂsed in a rainbow?
