Inventions
Every day it seems, new inventions surface that promise to add value to our day-to-day lives. But did you know, many of the inventions we interact with daily were developed entirely by accident?
Take the microwave, for instance. This accidental invention was developed by engineer Percy Spencer who, upon experimenting with a microwave-emitting magnetron, found that the candy bar in his pocket had begun to melt. Spencer was then able to harness this radiation into the microwave we use today to make snack time a speedy process!
Perhaps one of today’s most well-known accidental inventions, the potato chip, was born when a customer kept requesting that his french fries be sliced thinner and made crispier. Though chef George Crum responded with the chips as a joke, they quickly became a favorite snack worldwide!
Even the match is a result of accidental invention. When pharmacist John Walker was stirring chemicals, he noticed that the end of his stirring stick had dried into a hardened lump. When attempting to scrape the dried residue off, a flame sparked, and so did Walker’s idea to turn this accident into a helpful tool!
So, the next time your science experiment doesn’t go as planned, or you burn what you have cooked on the stove, keep in mind that some of today’s most valued inventions were discovered when the inventor least expected it!
Discoveries should always be made with the intention of a specific product or outcome.
Experiments don't always go as planned, but they can lead to discoveries.
Percy Spencer melted the candy bar using the Magnetron as a test for the early microwave.
The potato chip and match were two of the most important discoveries of modern time.
