The Iron Stomach competition is traditionally a multi-round team competition to eat a number of horrible things, held at Terracon.
It was first run in 1989, and has been run every year since.
It varies greatly in the nature of the different rounds. The only consistent event that has been in it most, if not every, year (can anyone remember a year it was not?) is Mars Bars in Coke, generally bobbing for fun size Mars Bars in two cans of Coca Cola, then drinking the Coke.
Other years have included rounds of raw squid, raw donut mix, (unintentionally) raw kidneys, skulling a beer, dry weetbix, smarties with chopsticks, and much more.
For several years this event was dominated by AndrewWilson who would enter the team competition as a one man team entering all events, and managed to win this way. Eventually this led to a horrible vomiting incident.
In 2008 CorrinBoyd had the ingenious idea of feeding the unwitting participants 'a raw curry', each round being an ingredient commonly found in a curry that was to be eaten raw - rice, an onion, coconut milk and possibly chilli but this author has trouble remembering. (Sober at Terracon? What is this nonsense?)
