Just before things really hit rough waters in Jaws, Chief Martin Brody catches a glimpse of the sea monster. Stumbling back into the wheel house he says to Quint: “You’re gonna need a bigger boat.” If you bring this mentality with you to Yonge-Dundas Square on May 10th you’ll be prepared to face a less monstrous, but perhaps equally crazy, sight: a nine tonne cake.

Dairy Queen is celebrating its cake’s 30th birthday and raising money for the Children’s Miracle Network by going for a Guinness World Record for the world’s largest ice cream cake. In order to break the current world record the cake will have to have a final weight in of well over eight tonnes—the equivalent of nuclear family of elephants. (Having a hard time wrapping your mind around this? Us too, check out the infographic.)

There are two main challenges with an elephant sized cake: building it and eating it. The first issue was tackled by a team of University of Toronto engineers who used protractors and levels and Beautiful Mind-like calculations to figure out how the whole thing wouldn’t collapse into a pile of soft serve. (Albeit a 21,000lbs pile.) The second issue requires some audience participation. Once the cake is assembled (the actual baking will be done offsite at a freezer facility north of the city), it will be a race against time to get Torontonians out and ready to eat a World Record. The cake assembly gets underway around 9:00am and Olympian Cheryl Bernard and Leafs GM Brian Burke will be onsite with SickKids Miracle Children to sing the Happy Birthday to the cake at noon. After that, it’s eating time. But be warned: You’re gonna need a bigger fork.
