In the 1990s, archeologists in Mexico City unearthed a 500-year-old skeleton near an ancient Aztec temple—a victim of human sacrifice. A grisly discovery, yes, but perhaps even more chilling was what the beheaded skeleton was holding: two small whistles, one in the shape of a skull. When a researcher blew into one of the tiny instruments, the horrifying sounds that emerged immediately captivated imaginations. One scholar described the noise as “a shriek of death.” - Gizmodo This whistle has been designed from a 3D scan of a Maya artifact. It is 3D printed with PLA plastic, a nontoxic plastic made from corn and guaranteed to scream.
