Video Squeaky sand

TLF ID M016308

This six minute video segment from Catalyst Two compares two beaches, one with white squeaky sand, the other with darker non-squeaky sand and their sand studied under a microscope. Dr Tim Senden attempts to shed some light on this mystery with the use of a visual model. Sand avalanches and the production of sound come into consideration. Science does not always have a definitive answer.
