Summer fun

I hope that you have seen this fountain in the new(-ish) section of the Detroit airport. What makes me think of it today is this brilliant video tribute to a certain evidently well-known fountain in Las Vegas. (If experiments like these aren't a good reason to study precalculus, then I don't know what is.) It didn't take long to stumble over the fact that the original in Las Vegas and the fountain in Detroit come from the same company, Wet Design.

And have you seen Chris Bliss juggling?
