A
sixty-foot high aircraft hanger in California had a (rather large) supply of fire-retardant foam released by...whatever (not, apparently a fire - although nobody can get inside to investigate).

The whole building was full, and the surrounding neighborhood was several feet deep in the stuff.
Anyone remember the great movie with Jack Lemmon (and other wonderful actors), "Mr. Roberts"?
Well, that laundry scene has met its match.
