It's a rainbow in the clouds!
The vid explains what it is and how it comes about.
that's cool, but..
what's with the creepy voice at the beginning?
...There was a voice?
Why does the video say "wonder-full?" Is that to imply "full of wonder?" "Wonderful" already means "full of wonder," as does any word with the suffix -ful (recalling 2nd grade English here). It bugs me when people try to be intelligent with grammar just to be incorrect after trying so hard (like using "I" when is should actually be "me").
