In twelfth grade, Steve Jobs engaged in some mischievous antics, reflecting his youthful creativity and a knack for invention. One notable prank involved him constructing an electronic metronome, a device typically used in music classes to maintain rhythm. During the process, he discovered that its sound resembled that of a bomb, which sparked an idea for a prank.
Jobs decided to take this auditory similarity further by dismantling big batteries, removing their labels, and securing them together. He then cleverly placed this assembly in a school locker, rigging it to create a startling effect. This episode illustrates his playful spirit and innovative thinking even at a young age.
