Volcanoes on Antarctica. Matthew takes you to an active volcano, whose caldera is partially submerged by the Southern Ocean. The geothermically heated ground heats up the normally freezing water making the water reasonable for a quick dip. This is almost the only place on earth where you can safely swim in an active volcano (with expert supervision of course and only when the volcano is quiet)! Matthew warns that you can't just go swimming in any volcano!!! This is an excerpt from the 23 minute documentary "Antarctica: the Frozen Continent at the Bottom of Earth" also known as "Mysteries of Antarctica", also available on YouTube. It is an educational documentary by a kid for kids. Teachers are free to use the full documentary in their school and classrooms. Leave Matthew a comment with the location of your school.
