" Yo-yo (Tagalog for "come back") evolved from a Philippine hunting tool made from a softball-size stone tied to a length of plant vine or a leather thong which enabled throwers to retrieve the weapon with a simple flick of the wrist (Hoffman 1996). The modern yo-yo thus has a great deal of physics, prehistory, and hunting lore encoded in its maple, beech, or plastic form (see below, Neuro-notes III). "
