In groups of three, student teams pushed their cardboard boats into the murky water and nervously worked together to row out to a deeper part of the lake.  With each shifting movement the uncertainty showed on their faces as the cardboard and packing tape contraptions strained under the weight of the three amateur sailors. Students called out directions to one another to keep these team-designed boats afloat. Hundreds of other students from the school, along with local media, stood on the shore cheering every moment.
