Slinky/Inventors
Seventy-two years ago, Richard James received a patent for the Slinky, describing “a helical spring toy which will walk on an amusement platform such as an inclined plane or set of steps from a starting point to successive lower landing points without application of external force beyond the starting force and the …
How did the Slinky changed the world?
The line was sold in 1998 to Poof Toys. US troops in Vietnam used them as mobile radio antennas. NASA has used them in zero-gravity physics experiments in Space Shuttles. Playroom to the classroom, climbing down stairways and floating in space the Slinky continues to educate and entertain the world today.
When was the Slinky first invented?
1943
The Slinky was invented and developed by American naval engineer Richard T. James in 1943 and demonstrated at Gimbels department store in Philadelphia in November 1945. The toy was a hit, selling its entire inventory of 400 units in ninety minutes.
What was Richard T James trying to make?
Career. In 1943 James was trying to develop a means for suspending sensitive shipboard instruments aboard naval vessels, even in rough seas, and was working with torsion springs when he accidentally dropped one. Seeing how the spring kept moving after it hit the ground, the idea for a toy was born.
What does the Slinky represent?
This wave is a movement of motion! This wave is called a transverse wave because the motion of the slinky is sideways to the motion along the slinky. It provides a model for waves moving along strings, for light waves(in particular linearly polarized light waves, and for seismic waves called S waves.
What is the point of a Slinky?
Invented by accident in a Philadelphia shipyard, the Slinky is a stack of coiled metal that becomes a bit of oscillating magic, a moving, traveling toy perfect for flipping head-over-heels to “walk” down stairs.
Why was the Slinky successful?
Rather than just falling to the floor, the spring ‘rolled’ downwards and landed on the ground the right way up, and it was this graceful motion that led to the birth of the iconic ‘slinky’ toy. Released in 1945, the toy sold all 44 of its original units in well under two hours.
When and how was the Slinky invented?
James experimented with different types of wire for a long time. Finally, in 1945, he settled on what he thought was the perfect combination. He used 80 feet of steel wire coiled into a two-inch helical spring. The Slinky was born!
How did he discover the Slinky?
Mechanical engineer Richard James invented the Slinky by accident. In 1943, he was working to devise springs that could keep sensitive ship equipment steady at sea. After accidentally knocking some samples off a shelf, he watched in amazement as they gracefully “walked” down instead of falling.
What nationality is Richard?

What have you noticed about the behavior of the slinky as it vibrates?
Notice that a wave travels along the Slinky from you to your partner. The vibrating parts of the Slinky move back and forth in the same direction as the wave is traveling. This time, sections of the Slinky move up and down, perpendicular to the direction in which the wave is traveling.
How does the slinky move with respect to the wave pulse?
Notice that a wave travels along the slinky. This wave is a wave of motion back and forth along the slinky which travels along the slinky, because the back and forth motion is in the same line as the direction of motion this is called a longitudinal wave. A circular motion wave moves along the slinky.
How did the slinky become a national sensation?
How a tension spring became a national sensation. The story of the Slinky begins with a mechanical engineer, a shipbuilding factory, and a mishap. It was 1943. The U.S. Navy needed ships for World War II as the Battle of the Atlantic raged in the oceans around Europe.
Who was the inventor of the Slinky spring?
A Slinky is a toy precompressed helical spring invented by Richard James in the early 1940s.
How big was the slinky when it was made?
In 1945, after about a year of tinkering, he found the perfect size: 80 feet of wire coiled into a two-inch helical spring. With the feeling that he was onto something, the WWII vessel engineer took out a $500 loan to start James Industries. Figures of a Slinky from the 1947 patent awarded to James Industries.
What is an example of cultural competency?
Cultural competence is a key practice in the learning frameworks, and the notion of cultural competence is embedded throughout. For example, principles within the learning frameworks relevant to cultural competence include fostering secure, respectful and reciprocal relationships, partnerships, high expectations and equity and respect for diversity.
