NASA Space Station On-Orbit Status 16 August 2004
“After both crewmembers prepared for today’s scheduled EPO (Educational Payload Operations) demo by reviewing the training instructions for toys and music instruments (Blues Harp, Chicken Shake and Puzzles), they set up the Lab camcorder and recorded the subsequent demo of both of them performing the Chicken Shake. [The Chicken Shake is an egg-shaped percussion instrument very similar to Cuban Maracas (only without the handles) that in Caribbean or South American orchestras are used in the percussion section to add to its variety of rhythms, textures and tone colors. The Chicken Shake EPO aboard ISS is a project of the Maryland Science Center.”
