Quiz Answer Key and Fun Facts
1. In 1942-51, when Harry Coover was working for Eastman Kodak and trying to create an improved gun sight he just ended up creating sticky, messy cyanoacrylate. Nine years later, the substance remained a mess but miraculously was still holding a tight bond without heat. Coover's accidental discovery led to the invention of what adhesive?

Answer: super glue

Dr. Harry Coover of Eastman-Kodak Laboratories thought his creation of cyanoacrylate signaled failure and only created a sticky mess. Years later he still had that sticky mess while working on a new design for airplane canopies. More tinkering, Coover and his team stumbled upon an amazing adhesive. Kodak sold the cyanoacrylate product as Super Glue. Coover later patented cyanoacrylate as a tissue adhesive for injured Vietnam War soldiers awaiting surgery.
2. Tinkering in his laboratory in New York in 1958, Wilson Greatbatch mistakenly picked up the wrong resistor while trying to record certain body functions. Recognizing its rhythm (one-second pauses between signals of 1.8 milliseconds), Wilson found this wrong choice was the perfect path to address cardiac challenges with what accidental invention?

Answer: implantable pacemaker

Instead of the 10,000-ohm resistor he wanted to use to record heart beats, Wilson Greatbatch grabbed a 1-megaohm one. The latter was the key to replicating and regulating heart rhythm, which lead Greatbatch to develop the first implantable pacemaker. With more than 300 patents, Greatbatch won the Lemelson-MIT Prize and was inducted into the National Inventors' Hall of Fame.
3. In 1945, while working for Raytheon Corp., Percy Spencer accidentally discovered the basis for the microwave oven after realizing the effect magnetron emissions had on something in his pocket. Lucky for quick-snack enthusiasts everywhere, what was in Spencer's pocket?

Answer: chocolate bar

The microwave rays from the magnetron had melted the chocolate bar in Perry Spencer's pocket. From this, Spencer was the first to investigate and realize the culinary benefits for microwave rays. Raytheon paid Spencer its then-standard $2.00 for employee inventions and filed a patent for a microwave cooking oven in 1945.
4. After an explosion of nitroglycerin at his factory killed his brother Emil and four others in Stockholm, Alfred Nobel searched for years to find a way to stabilize nitroglycerin. His efforts led to the invention of dynamite. What fortuitous event finally led Nobel to his discovery?

Answer: can of nitroglycerin broke and leaked

Alfred Nobel was shipping nitroglycerin in cans that were packed in kieselguhr, a sedimentary rock mixture. When one of the cans accidentally broke and leaked, Nobel realized that the kieselguhr perfectly absorbed nitroglycerin. This accident led Nobel to explore kieselguhr as a stabilizer for explosives, which ultimately leading to his dynamite invention.
5. In 1879, Constantin Fahlberg discovered the sweet taste of anhydroorthosulphaminebenzoic acid (trade name, Saccharin) while investigating coal tar derivatives at Johns Hopkins University. Sweet-toothed dieters thank Fahlberg for what mistake that led to his discovery?

Answer: forgetting to wash his hands

Constantin Fahlberg discovered the sweet taste of what would become Saccharin after, forgetting to wash up before heading home, he tasted the sweet substance on his hands while eating dinner rolls. Although Fahlberg made his discovery while working under the laboratory of Ira Remsen, and the two published their finding together in 1880, Fahlberg put only his name on his patent. Bitter at Fahlberg's betrayal and ultimate financial success, Remsen said: "Fahlberg is a scoundrel.

It nauseates me to hear my name mentioned in the same breath with him."
6. During a routine experiment with cathode rays in 1895, Wilhelm Roentgen luckily noticed that something across the room, and on the other side of a thick screen, was glowing. What "glowing" object led Roentgen to his invention of X-ray technology?

Answer: fluorescent cardboard

German physicist Wilhelm Roentgen realized that the radiated cardboard on the other side of the screen from the cathode emitter proved that light was passing through solid objects. His later investigation showed that X-rays would penetrate human flesh but not bone or lead. Being able to see inside the human body without surgery became a vital advancement in diagnostic medicine.
7. After a 1941 hunting trip with his dog in Switzerland, George de Mestral noticed burrs stuck in the dog's fur. Investigating further led de Mestral to invent what unique fastening system?

Answer: velcro

George de Mestral analyzed the burrs microscopically to discover the hooks that stuck burrs to fur and fabrics. Years of experimentation led to his discovery of a hook-and-loop fastener using nylon and polyester, which he branded as Velcro from the French words for velvet (velours) and hook (crochet). De Mestral patented Velcro in 1955.
8. In 1905, eleven-year-old Frank Epperson invented the popsicle by chance. What was his accident?

Answer: left his soda with stirring stick outside overnight

Thank goodness for Frank it was a cold night, because the soda froze around the stick and created a icy treat. In 1923, Frank Epperson patented his "frozen ice on a stick." Epperson later sold the invention and the Popsicle brand to the Joe Lowe Company in New York City.
9. In the late 1980s, scientists at Pfizer conducted clinical trials of the drug UK-92480. Although the trials were unsuccessful, they noted increased erections as a recurring side effect. This led the team to invent Viagra for erectile dysfunction. What condition was the original target of the UK-92480 trials?

Answer: hypertension and angina

Pfizer realized that UK-92480 (sildenafil) was not the miracle they had hoped for heart problems. The discovery of the drug's unintended side effect led Pfizer to investigate its use for the treatment of erectile dysfunction. Pfizer Inc. patented sildenafil 1996. On March 27, 1998, U.S. Food and Drug Administration approved the use of sildenafil for erectile dysfunction. Pfizer has marketed the drug as Viagra to great success - almost $2 billion in annual sales.
10. Alexander Fleming accidentally discovered a wonder drug in 1928 London when he saw a Petri dish had mold that was dissolving the bacteria around it. What random event led Fleming to discover penicillin?

Answer: he went on vacation

Sir Alexander Fleming did not come upon his penicillin discovery until he took a break. Fleming added staphylococci cultures to petri dishes, stacked them in a corner, and left for vacation. Upon his return, instead of the bacteria growing, Fleming was surprised to find a mold growing in the dishes instead.

His further inspection showed that the mold had created a byproduct stopping the staph growth and thereby giving Fleming credit for the world's first antibiotic. People the world over are thankful Fleming took a well-deserved break from his work to go on vacation.
