Over at FYFD is an interesting note on what those billowing clouds from rocket launches actually are [tumblr.com]:
What you’re seeing is not actually the rocket’s exhaust but the result of a launch pad and vehicle protection system known in NASA parlance as the Sound Suppression Water System.
There's also more detail at Interesting Engineering [interestingengineering.com] and NASA [nasa.gov].
Fascinating is a word I use for the unexpected.
