That old trick. I worked at a bowling alley in the 80’s that stocked dozens of 55 gallon drums of Zep laundry detergent. Us lane attendants skimmed the stock until we had 10 five gallon bucket loads. An accomplice that worked in the mall food court let us in a service door after hours and we dumped it all into a mall fountain with a waterfall that churned it up real good. It made a bigger mess than what we expected. Got on the news even. We were bored.
