Styrofoam cup after 3,100 feet underwater

Palmercup1
The coolest thing I own is a Styrofoam cup that went down to the bottom of the Palmer Deep, off the Palmer Peninsula in Antarctica. It was in a net bag tied to an oceanographer's water column sampler. I don't remember the name of the researcher, but she or he let everyone on the research vessel, including hanger-on science writers, send down a cup. The pressure of 10,400 3,100 feet of water compressed the tiny air bubbles inside the Styrofoam and turned a grande cup into an espresso cup. More reasons not to go scuba-diving at the bottom of the Palmer Deep.
