We all loved Sesame Street when we were little. The characters were attractive and engaging and I’ve often wondered how these puppets work. But how the mouth and the hands of the smaller ones work? How do they do the bigger ones like Snuffleupagus? If you wondered about the same questions, then we have the answers for you right here, WIRED recently released a video that goes behind-the-scenes with five of the puppeteers from Sesame Street and they explain to you how their puppets work. You’ll learn about Elmo, Big Bird, Mr. Snuffleupagus, Abby Cadabby, and Rudy! Check out the video below.
