Rainbow videos (i.e., Rainbow videos):
1. Unweaving the Rainbow | 0:16: Varying the refractive index of water. Short enough for the classroom.
2. The Greatest Double Rainbow | 0:27: A good double rainbow. Short enough for the classroom.
3. full circle rainbow | 0:28: You don't often see them from the ground---this is the ground of a very high building I think. I may have seen one from airplane once---on the other hand, that may have been a glory which is rainbow-like, but is caused by a different effect and has a smaller angular diameter measured from the solar optical axis. It was probably a glory. Short enough for the classroom.
4. How to simply make good rainbows in garden | 1:27: You can make your own rainbow with a garden hose. A few seconds is OK for the classroom.
5. triple rainbow | 0:18: A triple rainbow. I don't think this is an example of a supernumeray rainbow. Short enough for the classroom.
6. Rare Rainbow Cloud Phenomena known as a Circumhorizontal Arc | 0:33: This is probably a circumhorizontal arc which is ice crystal phenomenon and NOT a raindrop phenomenon like rainbows. Short enough for the classroom.
7. How a Rainbow Works | 3:17: Too long for the classroom.
8. Regenbogen | 2:22: The musical. See the second version Wenn's zum Regenbogen geht | 2:39 with lyrics---in German. The singer is Annett Louisan (1977--). Too long for classroom.
