The Exploratorium is a museum of science, technology, and arts in San Francisco, California. Founded by physicist and educator Frank Oppenheimer in 1969, the museum was originally located in the Palace of Fine Arts and was relocated in 2013 to Piers 15 and 17 on San Francisco's waterfront.

Tim Hunkin is an English engineer, cartoonist, writer, and artist living in Suffolk, England. He is best known for creating the Channel Four television series The Secret Life of Machines, in which he explains the workings and history of various household devices. He has also created museum exhibits for institutions across the UK, and designed numerous public engineering works, chiefly for entertainment. Hunkin's works are distinctive, often recognisable by his unique style of papier-mâché sculpture, his pen and ink cartoons, and his offbeat sense of humour.
