He Put the "Tupper" in Tupperware

Home parties are everywhere now - Longaberger, Avon, Mary Kay, Silpada, Pampered Chef - and those are just the ones my mom has had in the past year .(I kid. She'll kill me when she reads this.) But none of those companies would exist today if Earl Tupper hadn't patterned some polyethylene after a paint can lid.

Tupper was working for the plastics division of DuPont during WWII, but became interested in finding a peacetime use for the company's polyethylene once the war was over.

Tupper tried the material in various molds (he had amassed an interesting personal collection of molding machines) and tinkered with the formula until he found a perfect consistency for dishes and dinnerware. He developed Tupperware's signature airtight lid by observing how well a paint can lid kept its contents fresh and duplicating it in plastic. Keen observations like these made Tupper's "Wonderbowls" the winner of numerous design contests; the dishes were even sold at a standalone store on Fifth Avenue in New York. Still, Tupper just wasn't making any real money on his product... and then there was Brownie.

An extroverted single mom, Brownie Wise's sales of Tupperware single-handedly outdid the sales at the actual Tupperware store. When Tupper found out about her "home party" method of sales - essential for demonstrating that patented Tupperware "burp" seal - he promoted her to vice president of the company. The duo were extremely successful until they had a falling out and Tupper abruptly booted her from the company in the late '50s. She left with just a year's advance salary and no stock holdings; Tupper sold Tupperware Home Parties — Brownie's division — for $16 million about a year later. He also divorced his wife and bought an island (and you thought a mid-life crisis Porsche was bad).

Just because he was done with the 'ware, Tupper didn't exactly retire. He had so many inventions in his brain he had to carry a notebook at all times to keep them straight. Among his ideas: a "Bite and Wound Sucker," assorted combs and a no-drip ice cream cone. As you can probably guess, none of them quite reached the same success as Tupperware.

The Carrot Test

Ding dong! Carrot calling! Long before Avon patented their "Avon calling" catchphrase, Tupperware saleswomen were practicing "Carrot calling," a technique that challenged women to put carrots in Tupperware instead of where they usually stored veggies to see which method kept them fresh longer. Parties were often booked after it became evident how much better the carrots fared in Tupperware.

This Ketchup Will be Sold by the Slice

Slice of Sauce

Some have called it a food abomination. Others believe it will be the next big thing in food disruption. It’s ketchup taken out of its customary bottle or squeeze packet and distributed via cheese-like slices. And it may be coming to a store near you.

Slice of Sauce slices appear on a cutting board
Slice of Sauce

In March 2018, a company called Bo’s Fine Foods organized a Kickstarter for Slice of Sauce, a new—and highly controversial—method of packaging the condiment. Each retail pouch will contain eight “slices” of dried ketchup that Bo’s argues has several advantages over the bottled version. The ketchup won’t soak a piece of bread or sputter out in watery blasts: Consumers will get an even application of it every time, with the ketchup distributed equally among each bite. Each slice has 30 calories and 5 grams of sugar, with no high-fructose corn syrup or preservatives.  

As Vice pointed out, the idea is similar to chef Ernesto Uchimura’s “ketchup leather,” a novelty food hack he created in 2014.

While Slice of Sauce may help prevent apparel-related squirting mishaps, it’s not entirely clear whether people will embrace this rogue approach to dispensing tomato paste. The idea of freezing and then serving slices of peanut butter was met with scorn in 2017. Today reports that some Twitter critics have refused to acknowledge a “ketchup fruit roll-up” while others promise to “make a huge scene” if confronted with it while dining out. We’ll see if Slice of Sauce can dispense some unconventional success when it starts shipping to Kickstarter backers and select retail stores in June.

19 Things You Might Not Know Were Invented by Women

Necessity isn't the only mother of invention. Though it wasn't always easy to get patents or the credit they deserved, women are responsible for many items we use today.

1. THE PAPER BAG

America got a brand new paper bag when cotton mill worker Margaret Knight invented a machine to make them with a flat square bottom in 1868. (Paper bags originally looked more like envelopes.) A man named Charles Annan saw her design and tried to patent the idea first. Knight filed a lawsuit and won the patent fair and square in 1871.

2. KEVLAR

Lightweight, high-tensile Kevlar—five times stronger than steel—will take a bullet for you. DuPont chemist Stephanie Kwolek accidentally invented it while trying to perfect a lighter fiber for car tires and earned a patent in 1966.

3. THE FOOT-PEDAL TRASH CAN

Lillian Gilbreth improved existing inventions with small, but ingenious, tweaks. In the early 1900s, she designed the shelves inside refrigerator doors, made the can opener easier to use, and tidied up cleaning with a foot pedal trash can. Gilbreth is most famous for her pioneering work in efficiency management and ergonomics with her husband, Frank. Two of their 12 children, Frank Jr. and Ernestine Gilbreth, humorously wrote about their home/work collaborations in the book Cheaper by the Dozen.

4. MONOPOLY

Elizabeth Magie created The Landlord's Game to spread the economic theory of Georgism—teaching players about the unfairness of land-grabbing, the disadvantages of renting, and the need for a single land value tax on owners. Fun stuff! Magie patented the board game in 1904 and self-published it in 1906. Nearly 30 years later, a man named Charles Darrow rejiggered the board design and message and sold it to Parker Brothers as Monopoly. The company bought Magie's patent for the original game for $500 and no royalties.

5. WINDSHIELD WIPERS

Drivers were skeptical when Mary Anderson invented the first manual windshield wipers in 1903. They thought it was safer to drive with rain and snow obscuring the road than to pull a lever to clear it. (Another woman inventor, Charlotte Bridgwood, invented an automatic version with an electric roller in 1917. It didn't take off, either.) But by the time Anderson's patent expired in 1920, windshield wipers were cleaning up. Cadillac was the first to include them in every car model, and other companies soon followed.

6. DISPOSABLE DIAPERS

Marion Donovan didn't take all the mess out of diaper changing when she patented the waterproof "Boater" in 1951. But she changed parenting—and well, babies—forever. The waterproof diaper cover, originally made with a shower curtain, was first sold at Saks Fifth Avenue. Donovan sold the patent to the Keko Corporation for $1 million and then created an entirely disposable model a few years later. Pampers was born in 1961.

7. THE DISHWASHER

Patented in 1886, the first dishwasher combined high water pressure, a wheel, a boiler, and a wire rack like the ones still used for dish drying. Inventor Josephine Cochrane never used it herself, but it made life easier for her servants.

8. LIQUID PAPER

In the days before the delete key, secretary Bette Nesmith Graham secretly used white tempera paint to cover up her typing errors. She spent years perfecting the formula in her kitchen before patenting Liquid Paper in 1958. Gillette bought her company in 1979 for $47.5 million. And that's no typo.

9. ALPHABET BLOCKS

Children don't read books by anti-suffrage author Adeline D.T. Whitney these days—and that's probably for the better. But the wooden blocks she patented in 1882 still help them learn their ABCs.

10. THE APGAR SCORE

Life is a series of tests, starting with the Apgar, named after obstetrical anesthesiologist Dr. Virginia Apgar. In 1952, she began testing newborns one minute and five minutes after birth to determine if they needed immediate care. About 10 years later, the medical community made a backronym—an acronym designed to fit an existing word—to remember the criteria scored: Appearance, Pulse, Grimace, Activity, and Respiration.

11. MARINE SIGNAL FLARES

Communication between ships was once limited to colored flags, lanterns, and screaming things like "Thar she blows!" really loudly. Martha Coston didn't come up with the idea for signal flares all by herself. She found plans in a notebook that belonged to her late husband. The determined widow spent 10 years working with chemists and pyrotechnics experts to make the idea a reality. But she was only named administratrix in the 1859 patent—Mr. Coston got credited as the inventor.

12. THE CIRCULAR SAW

A weaver named Tabitha Babbitt was the first to suggest that lumber workers use a circular saw instead of the two-man pit saw that only cut when pulled forward. She made a prototype and attached it to her spinning wheel in 1813. Babbitt's Shaker community didn't approve of filing a patent, but they took full advantage of the invention.

13. RETRACTABLE DOG LEASH

New York City dog owner Mary A. Delaney patented the first retractable leading device in 1908. It attached to the collar, keeping pooches under control, while giving them some freedom to roam. Incidentally, someone named R.C. O'Connor patented the first child harness 11 years later. Coincidence? Maybe.

14. SUBMARINE TELESCOPE AND LAMP

It's difficult to find any in-depth information about early inventor Sarah Mather. Her combination telescope and lamp for submarines, patented in 1845, speaks for itself.

15. FOLDING CABINET BED

Sarah E. Goode's folding cabinet bed didn't just maximize space in small homes. In 1885, it made her the first African-American woman with a U.S. patent. The fully functional desk could be used by day and then folded down for a good night's sleep. The Murphy bed came along some 15 years later.

16. THE SOLAR HOUSE

Biophysicist Maria Telkes's place was in the house—the very first 100 percent solar house. In 1947, the Hungarian scientist invented the thermoelectric power generator to provide heat for Dover House, a wedge-shaped structure she conceived with architect Eleanor Raymond. Telkes used Glauber's salt, the sodium salt of sulfuric acid, to store heat in preparation for sunless days. Dover House survived nearly three Massachusetts winters before the system failed.

17. SCOTCHGARD

Apparently, it takes a stain to fight one. In 1952, 3M chemist Patsy Sherman was perplexed when some fluorochemical rubber spilled on a lab assistant's shoe and wouldn't come off. Without changing the color of the shoe, the stain repelled water, oil, and other liquids. Sherman and her co-inventor Samuel Smith called it Scotchgard. And the rest is ... preserving your couch.

18. INVISIBLE GLASS

Katharine Blodgett, General Electric's first female scientist, discovered a way to transfer thin monomolecular coatings to glass and metals in 1935. The result: glass that eliminated glare and distortion, which revolutionized cameras, microscopes, eyeglasses, and more.

19. COMPUTERS

Women in computer science have a role model in Grace Hopper. She and Howard Aiken designed Harvard's Mark I computer, a five-ton, room-sized machine in 1944. Hopper invented the compiler that translated written language into computer code and coined the terms "bug" and "debugging" when she had to remove moths from the device. In 1959, Hopper was part of the team that developed COBOL, one of the first modern programming languages.
