"Oklahoma State University (OSU)"
(11th place overall; 15th in paper; 13th in presentation; 4th in product)


OSU relied on 3 people to deliver their presentation.  They used 1 screen and presented their effort from a business standpoint.

Following the team introduction there was a uncomfortable delay while getting the computer booted.  But the team handled this well and began undaunted by elaborating on their management and goals.

They explained how they included Buckeye UltraFiber to strengthen their mix in order to reduce cracking.  Then, the team explained their design criteria and outlined how they went about mix design.

They said that they tested 32 different mixes and explained how an appropriate balance was made between strength and weight.  Then the team detailed the aggregates and admixtures incorporated into the mix.

Mold construction came next and the team explained how this was done.  Then, they elaborated on canoe construction.  They explained how they did their 4 layer lay-up and elaborated on the methods used to cure and finish their boat.  The team mentioned how little time it took to place their canoe.  Then the team highlighted the main features and specifications for their entry.
