“The Darwin Beer Can Regatta is an event which has been held annually since 1974 in Darwin, Northern Territory, Australia at Mindil Beach. Participants create boats using empty beer cans, soft drink (soda) cans, soft drink bottle and milk cartons. The vessels are not tested for seaworthiness, prior to water events, and those that fall apart are part of the day's entertainment. A great many sundry events go along with the regatta, including concerts, a thong-throwing contest and the "Henley-on-Mindil" competition (named after the Henley-on-Todd Regatta), where participants run their "boats" around like Flintstones cars”. – Wikipedia
