Iceberg-tipping

Alexis Madrigal, in the Atlantic, on the history of iceberg-towing schemes:

Mid 1800s: According to the Encyclopedia of Antartica, small icebergs were towed from southern Chile up to Valparaiso as part of the brewery supply chain. A Chilean researcher said, "The icebergs were towed by ships of the conventional type. Sometimes the icebergs were supplied with sails to utilize the prevailing winds. The ice was used for refrigerating purposes in the breweries and was generally substituted for artificial ice." Apparently, the business continued until about the turn of the century.

Via the blog formerly known as the Plank. Tangentially, the Wikipedia article on planking is priceless, esp. the "notable incidents" section:

• The game made news in September 2009, when seven doctors and nurses working at the Great Western Hospital in Swindon, England were suspended for playing the lying down game while on duty.^{[13][13][14][15]}

• On 13 May 2011, a 20-year-old man from Gladstone in central Queensland was charged for allegedly planking on a police vehicle.^[16]

• On 15 May 2011, Acton Beale, a 20-year-old man, plunged to his death after reportedly "planking" on a seventh-floor balcony in Brisbane, Australia.^[17]
