How can we design a personal flotation device (PFD) for a can of soup that can be put on it by one group member in less than 20 seconds and allow it to float for more than one minute using the available supplies?

Students will learn about PFDs, engage in the engineering of a PFD to meet specific criteria, design, revise, and redesign their PFDs, and evaluate design solutions that best meet the design criteria.
