Disruptive Technology in Making Ice Cream
This chapter explores the challenges faced by a missionary and abolitionist in Philadelphia in the 1800s, Nancy Johnson, in making ice cream more affordable. It discusses how she searched for solutions in other industries, such as using water pails to keep the ice cream cold and attaching spatulas to a hand grinder for easier stirring. The chapter also examines the concept of disruptive technology and problem-solving strategies.
