Narwhal Automaton: a flick of a switch sends this narwhal swimming via slender linkages to a rotating cam shaft in the base. Wonderful use of mechanical translation from rotational motion to the complex motion of this long toothed cetacean. This kinetic sculpture’s motor is powered by one AAA battery which also turns a music box. ➡️ Follow the link in my profile for information on where to get this device and many other amazing items featured here on @physicsfun #linkage #physicsfun #narwhal #ph
