A YouTube series that hearkens back to characters and situations from old silent films, Jiwi’s Machines mixes a love for Rube Goldberg Machines with an ode to comedy greats like Charlie Chaplin or Buster Keaton.

The series’ creator and star Joseph Herscher is a kinetic artist that relies not only on physical comedy but on physics, too. In this series of Science Extras, Jiwi and assistant Luke demonstrate and explain different ideas that help power Jiwi’s Machines. Above, Dominoes.
