Look Inside a Rattlesnake’s Rattle | Deep Look Video

A rattlesnake’s rattle isn’t like a maraca, with little bits shaking around inside. So how exactly does it make that sound?

This is another installment of the PBS Deep Look series. If no film or link appears in this email, go to the blog to view it by clicking on the blog title above. If the film stops & starts in an annoying manner, press pause (lower left double bars ||) to let it buffer and get ahead of you.   [Chuck Almdale]
