The Seesaw and the Shoes
11 mins
This short shows how two objects led to important discoveries. Children playing with a seesaw inspire French physician Rene Laennec to invent the stethoscope, and a pair of shoes made of caoutchouc lead Charles Goodyear to discover the process for vulcanizing rubber.
