Making the cups for the pressure test.

As we prepare to leave on our trip the Earth science classes at the Senior Academy are preparing their styrofoam cups for a trip to Davy Joneses locker. The students have measured the mass of their cups (pre-crush) as well as the liquid volume these cups hold (ideally 354 ml), the height and mouth diameter in centimeters. These cups will be attached to a CTD (Conductivity, Temperature, and Depth) rosette that we will send to the bottom sometime while we are on our Stratus 10 cruise. During the decent the cups will be subjected to immense pressure and squashed. Once we return to the classroom the students will re-measure their cups and determine the percentage of change based on the new volume the cups can hold and the other new measurements that the cups will have.
