A Nobel laureate and a flea circus join forces for an unforgettable demonstration of inertia

The Physical Science Study Committee (PSSC) was formed in 1956 at the Massachusetts Institute of Technology with the mission to create science-education materials for US high-school classrooms. Extracted from a PSSC film from 1959, the first half of this short video finds the Nobel Prize-winning physicist E M Purcell from Harvard University detailing the basics of inertia with some help from a frictionless dry-ice puck – which, by his exceptionally impassive account, is a thing that’s ‘fun to play with’. The video gets a good deal stranger in the second half, which takes viewers on a field trip to Hubert’s Museum in New York City: a long-since defunct cabinet of 10-cent curiosities that was once a Times Square mainstay. There, Hubert’s famed in-house flea circus puts its considerable talents on display as the ringmaster leads a one-of-a-kind inertia demonstration. It all makes for an impressive proof of concept, and some delightfully dated fun.
