Accidental Inventions

 

It's quite intriguing to ponder the origins of various inventions. Consider the likes of the slinky, silly putty, and potato crisps – how did they come about? Surprisingly, many of these renowned innovations were actually the unintended outcomes of scientists' pursuits in different directions.

​

Slinky
Inventor: Richard Jones, a naval engineer
Initial Endeavour: Developing a power monitoring meter for naval battleships
Unintended Outcome: While handling tension springs, one happened to fall to the ground. It continued bouncing around after hitting the floor, thus giving rise to the concept of the slinky.

​

Penicillin
Inventor: Sir Alexander Fleming, a scientist
Initial Goal: Pioneering a "wonder drug" capable of combating diseases. Ironically, the breakthrough came when Fleming discarded his experimental materials.
Unintended Discovery: Fleming observed that a discarded Petri dish was home to a mould dissolving the surrounding bacteria. Cultivating this mould separately revealed a potent antibiotic: penicillin.

Chocolate-Chip Biscuits
Inventor: Ruth Wakefield, Owner of the Toll House Inn
Original Aim: Crafting regular chocolate biscuits
Unintended Creation: While preparing biscuit batter, Wakefield realised she lacked baker's chocolate. In a substitution attempt, she added broken pieces of sweetened chocolate. Instead of melting, these bits remained intact, giving birth to the iconic chocolate-chip biscuit.

​

Potato Crisps
Inventor: George Crum, chef at the Carey Moon Lake House in Saratoga Springs
Initial Attempt: Frying a plate of potatoes
Unintended Result: Responding to a customer's repeated request for thinner and crispier fries, Crum sliced the potatoes razor-thin and fried them extensively. To his astonishment, the customer adored the crispy outcome, thus sparking the creation of potato crisps.

​

Pacemaker
Inventor: John Hopps, an electrical engineer
Original Pursuit: Investigating hypothermia, Hopps was experimenting with radio frequency heating for rewarming the body.
Unforeseen Development: While exploring this concept, Hopps recognised the potential to restart a stopped heart via artificial stimulation, which eventually led to the invention of the pacemaker.

​

Silly Putty
Inventor: James Wright, an engineer at General Electric
Initial Objective: During World War II, to create a rubber substitute from silicon as a material alternative.
Unintentional Innovation: A mishap occurred during a silicon oil test, where Wright inadvertently introduced boric acid to the mixture. This led to a peculiar, bouncy substance – Silly Putty – which, although lacking practical utility, became a popular toy.

​

Microwave Ovens
Inventor: Percy Spencer, an engineer with the Raytheon Corporation
Original Project: Spencer was engaged in radar-related research employing a new vacuum tube.
Unplanned Breakthrough: Spencer's sweet bar melted in his pocket while conducting experiments, prompting him to test popcorn in the machine. The resulting popping indicated the revolutionary potential of microwave ovens.

​

Saccharin (Artificial Sweetener)
Inventor: Constantine Fahlberg, a researcher at Johns Hopkins University
Initial Focus: Investigating the oxidation of o-toluenesulfonamide (a chemical compound).
Accidental Outcome: Fahlberg's hands remained unwashed after working in the lab, and the chemical residue on them turned his bread unusually sweet. Recognising the value, he patented and mass-produced the artificial sweetener, saccharin.

​

Fireworks
Inventor: An unknown cook in China
Initial Experiment: According to legend, the cook was experimenting in the kitchen.
Unintended Result: Mixing charcoal, sulphur, and saltpetre – common kitchen ingredients of the time – resulted in an explosive mixture when compressed in a bamboo tube, giving birth to fireworks.

​

Scotchgard
Inventor: Patsy Sherman, a chemist at 3M
Initial Assignment: Developing a fuel-resistant rubber material for jet aircraft.
Unexpected Revelation: Accidentally spilling the experiment on her shoe, Sherman noticed that the spilled area remained clean while the rest of the shoe became dirty. This serendipitous incident led to the creation of scotchguard, a stain-resistant compound.

​

Corn Flakes
Inventor: The Kellogg brothers, John and Will
Original Venture: Boiling grains to create a dietary product.
Unplanned Outcome: Leaving boiled grain on the stove inadvertently led to a mouldy mixture that, after refinement, resulted in the invention of the iconic corn flakes.

​

LSD as a Drug
Inventor: Albert Hofmann, a chemist
Initial Objective: Exploring lysergic acid derivatives in a Basel laboratory.
Unintentional Occurrence: Hofmann accidentally ingested a small amount of LSD during his research, leading to the first recorded LSD trip.

​

Ink-Jet Printers
Inventor: A Canon engineer
Innovation Genesis: Accidentally pressing a hot iron against a pen caused ink to spurt from the pen's point later on. This principle laid the foundation for inkjet printers.

​

Post-it Notes
Inventor: Spencer Silver, a researcher at 3M Laboratories
Initial Goal: Crafting a powerful adhesive
Unplanned Emergence: While working, Silver produced an adhesive weaker than existing options. It adhered but could be effortlessly removed without leaving a mark. Years later, a colleague applied the adhesive to small paper pieces for marking, leading to the birth of post-it notes.

​

X-Rays
Inventor: Wilhem Roentgen, a physicist with an unconventional approach
Original Investigation: Exploring cathodic ray tube properties
Unanticipated Outcome: Observing fluorescent papers illuminated by his machine's rays through its opaque cover, Roentgen inadvertently discovered X-rays.

This array of inventions, each born from unintended paths, showcases the remarkable potential hidden within serendipity and mistakes.
