Slinky

Sound waves travel through a slinky by causing the coils of the slinky to vibrate back and forth. The kinetic energy from these vibrations is transferred along the length of the slinky, allowing the sound wave to propagate. The density and elasticity of the slinky material help in transmitting the sound energy effectively.

The human slinky prop is essentially a long, stretchy fabric tube that is able to expand and contract. When a person wears it, they can manipulate their arms and body to create the illusion that the slinky is moving in a Slinky-like manner. It relies on the person's movements and the fabric's elasticity to create the effect.

A slinky primarily uses potential energy while stretched or compressed due to its elasticity. When released, this potential energy is converted into kinetic energy as the slinky moves back and forth. Friction and air resistance may also play a small role in absorbing some of the energy as heat.

Richard James invented the slinky in 1943. The idea for the slinky came about when he accidentally knocked over a spring and noticed how it moved in a slinking manner. He later developed it into the popular toy we know today.

Betty James, the wife of the inventor of the slinky, Richard James, passed away in 2008 at the age of 90.

Betty James saw a spring fall off a table and noticed how it "walked" instead of falling. She convinced her husband Richard James to develop a toy out of the spring, which became the Slinky. They later founded James Industries to produce and market the toy.

No one discovered it... The Slinky was an accident. Richard James was working on something when one of his springs fell to the ground. He saw how the spring didn't stop moving, and came up with an idea for a new toy. Richard James, using a different kind of spring, recreated that movement.

The plastic wire in a slinky is typically made from polypropylene or PVC, which are both types of thermoplastics known for their flexibility and durability.

how many feet of wire is in a slinky?

80 feet

If a slinky is tangled or bent out of shape, you can try gently pulling and twisting it back into its original form. If the slinky is broken or stretched out, it may be difficult to repair and you might need to replace it. Regularly untangling the slinky after use can help prevent it from getting damaged.

They vary in length, but are usually about 87 feet long at maximum.

The slinky was invented by Richard James in 1945 when he accidentally knocked over a coiled spring and saw how it "walked" down some books. Recognizing its potential as a toy, he and his wife Betty developed the idea further and introduced the slinky to the market.

The Slinky, like all objects, tends to resist change in its motion. Because of this inertia, if it were placed at the top of the stairs it would stay at rest without moving at all. At this point it has potential or stored energy. But once it is started down the stairs and gravity affects it, the potential energy is converted to the energy of motion or kinetic energy and the Slinky gracefully tumbles coil by coil down the stairs.The physical properties of the slinky determine how quickly it moves under the influence of gravity. Although its movement may look simple, from a scientific point of view the motion is quite complex. As the slinky moves down the steps, energy is transferred along its length in a longitudinal or compressional wave, which resembles a sound wave that travels through a substance by transferring a pulse of energy to the next molecule. How quickly the wave moves depends on the spring constant and the mass of the metal. Other factors, such as the length of the slinky, the diameter of the coils and the height of the step must be considered to completely understand why a slinky moves as it does.

The slinky was invented in 1943 by Richard James, a naval engineer. It was originally created as a tension spring for naval instruments but became a popular toy after accidentally dropping it and observing its unique movements.

The slinky was invented in 1943 by Richard James.

The inventor of the slinky is Richard James, who had help from his wife, Betty James. Richard James was an engineer employed by the Navy. In 1943, while working on anti-vibration technology, a torsion spring fell of the table. The movement of the spring caught his eye, and the idea for the Slinky was born. He told Betty, "I think I can make a toy out of this." Betty searched for the perfect name, she found it in the dictionary - Slinky: graceful, sinuous, and sleek. In 1945, after years of working to find the right balance of metals for the spring and engineering the equipment to produce it, Richard and Betty took 200 Slinkies to Gimbel's Department store in Philadelphia. Worried that the toy might not catch on, Betty convinced a friend to buy the first one. They had no need to worry. Slinkies were a giant hit. They sold all 400 slinkies in 90 minutes.

Richard and Betty James then founded the James Spring and Wire Company, which later became James Industries. In 1948, the opened a factory in Philadelphia, to manufacture their toy. For a while, both the business and the James family enjoyed success. However, in the 1960s, Richard James experienced a "religious awakening" and joined a Bolivian cult. He donated his wealth to his newly found religion, bankrupted his company, and left his wife and six children, including an infant for Bolivia. He told Betty that she could either run the company or sell it; he didn't care. Faced with the difficult challenge of becoming the breadwinner of a large family during a time that women were expected to remain at home and care for the children, Betty James took the helm of James Industries as its CEO. Through strength, intelligence, hard work, and sheer willpower, Betty James rescued the company and the Slinky from ruin. She relocated her family and company from Philadelphia to her hometown of Hollidaysburg, Pennsylvania.

Under the care of Betty James, the Slinky was revitalized. Betty began an advertising campaign with the famous jingle, "It's a Slinky. It's a Slinky. Fun for a girl or a boy." But she didn't stop there. Betty James expanded the Slinky family by inventing new toys, which include Crazy Eyes, Slinky Jr., and Slinky Pets, including the ever memorable Slinky Dog, who was featured in the films Toy Story and Toy Story 2. In 2001, Betty James became the second woman to be inducted in the the Toy Hall of Fame.

The Slinky got its name from a Swedish word meaning "sleek and sinuous," which perfectly describes the way it moves in a continuous flow of undulating motion. Its inventor, Richard James, thought the word captured the toy's essence and appeal.

The slinky has provided entertainment and inspiration for creative play. It has also been used in educational settings to demonstrate principles of physics. Additionally, the slinky has become an iconic toy that has sparked nostalgia in many people.

The slinky was invented as a toy in the 1940s and became popular for its unique bouncing and walking capabilities. It entertained children and adults alike, bringing joy and amusement to many. It also became a symbol of innovation and creativity in toy design.

Richard T. James was an American engineer, best known for being the inventor of the popular spring toy 'Slinky' in 1940, which received the popular nickname from his wife Betty. He was born the 1st of January of 1914.

You put it in walking position, then you blow on it as hard as you can. It'll walk in a jiffy then!

The Slinky was made out of steel.

Put it in hot (but not boiling) water for a minute or two, then take it out and rest something heavy on top of it until it cools. It should be better if not perfect then.
