From microwaves to bug spray: 12 items originally made for the military

Duct tape

One of the most useful things to have around is, without a doubt, duct tape. This product can help fix an endless number of everyday problems in virtually any environment.

This adhesive tape was invented during World War II by a division of Johnson & Johnson called Revolite. It was initially used to seal ammunition cases because of its water-resistant properties.

GPS

The GPS technology we all use daily on our smartphones to navigate from point A to point B was originally developed by the U.S. military. It was designed to track the position of military units and help them find their way efficiently across any terrain —much like how we use it today for civilian purposes.

Internet

Few technologies have become such a big part of our lives in just a couple of decades like the Internet. Its origins trace back to the 1970s, when the Defense Advanced Research Projects Agency (DARPA) created an interconnected network linking military centers to enable resource sharing.

The connection of commercial networks and enterprises by the early 1990s, along with the advent of the World Wide Web, marked the beginning of the transition to the modern Internet.

Walkie-talkie

From children’s toys to invaluable communication devices used in critical situations, walkie-talkies are a common fixture in modern life. Their development during World War II has been variously credited to Donald Hings, radio engineer Alfred J. Gross, Henryk Magnuski, and engineering teams at Motorola.

Initially used by infantry, similar designs were created for field artillery and tank units. After the war, walkie-talkies spread to public safety and eventually commercial use.

Microwave oven

Believe it or not, microwave cooking was accidentally discovered during a military-related project just after World War II.

In 1946, Percy Spencer, a scientist working on a magnetron at Raytheon, noticed that a peanut cluster candy bar in his pocket had melted from the magnetron’s microwave radiation. Curious to experiment further, he brought in some kernels of corn and made the first-ever microwave popcorn—leading to the invention of the microwave oven.

Super glue

In 1942, a research chemist working for a defense contractor was developing a high-precision targeting sight for weapons. Although the project didn’t produce the expected results, the resulting product was incredibly sticky , leading to the creation of the now-famous Super Glue.

Aviator sunglasses

Aviator sunglasses were developed in the 1930s as a lighter alternative to the bulky goggles worn by pilots during the early years of aviation. Those goggles were heavy, uncomfortable to wear, and prone to fogging up mid-flight.

Colonel John Macready of the U.S. Army Air Corps helped develop the first set of aviator sunglasses, which became known as Ray-Bans—named for their purpose: banning the sun’s rays from a pilot’s eyes.

Packaged salad mixes

The bags of packaged salad mixes found at any local supermarket use "modified atmosphere packaging" to delay ripening and spoilage.

This technology was developed in the 1960s through a collaboration between Whirlpool Corp. and the U.S. Navy to send fresh lettuce and celery to troops in Vietnam .

Bug spray

The active ingredient in most insect repellents, known as DEET, was developed by the U.S. Army in 1946 for use by military personnel operating in insect-infested areas . The product’s success led to its commercial release.

Disposable sanitary pads

During World War I, Kimberly-Clark invented Cellucotton, a wood pulp–based material designed to be more absorbent and cost-effective for use in bandages.

After the war, the company discovered that Army nurses had repurposed Cellucotton as sanitary napkins , which inspired the creation of Kotex—the first disposable sanitary pads.

Frozen juice concentrate

In 1942, USDA scientists developed frozen concentrated orange juice during World War II to help provide soldiers with sufficient Vitamin C . Although it was never distributed to the military, the product was later introduced to consumers by Minute Maid.

WD-40

WD-40, now a common household product, was originally developed in 1953 to prevent rust and corrosion on the outer shell of the Atlas missile . Created by the Rocket Chemical Company, the name WD-40 stands for "water displacement," with the "40" representing the number of attempts it took to perfect the formula.
