Who Invented Slime and How?

How Was Slime Invented?

What is Slime?

Slime is a stretchy and gooey substance that has gained popularity as a children's toy and stress relief tool. It can be played with in different ways, and its unique texture has drawn many fans.

The Early Beginnings of Slime

Slime was first introduced in the early 1970s as a toy contained in a plastic trash can. The toy was green and marketed as "Slime," gaining popularity among children who loved playing with its stretchy and sticky nature. However, the initial concept of slime was not entirely new, as the substance had been used by Hammer Laboratories for educational purposes in the 1950s.

The Inventor of Slime

The inventor of Slime is Harvey Chin. Chin worked as a chemical engineer in the toy industry and developed the first slime toy. The idea of slime came to him when he observed how a specific chemical, polyvinyl alcohol, reacted when mixed with boric acid. After mixing the two compounds, Chin was fascinated by the substance's slimy consistency and potential as a children's toy.

Slime's Evolution

After the initial release of the Slime toy, Chin continued to perfect the formula, adding colors and fragrances to make it more appealing to children. The toy also underwent a name change, going from "Slime" to "Green Goop" before becoming "Slime" again. In the 1980s, a new ingredient was added to the Slime formula called guar gum, a natural thickener. This improved the substance's texture, making it even stretchier and more enjoyable to play with.

The Rise of Slime's Popularity

In recent years, slime has experienced a resurgence in popularity, with thousands of videos featuring the toy being posted on social media platforms like Instagram and YouTube. The trend has led to the creation of new types of slime that are even more stretchy and have unique textures, such as fluffy slime, crunchy slime, and glitter slime. Additionally, many DIY tutorials have been created online, allowing children to create their own slime at home using common household items like glue and borax.

The Science Behind Slime

Slime's unique texture is due to its non-Newtonian properties, which means it does not follow the typical behavior of fluids or solids when under stress. Slime acts as a liquid when left alone, but when pressure is applied, it solidifies and can be shaped into different forms. This property makes slime an excellent stress relief tool, as it can be manipulated in different ways without losing its original shape. Furthermore, creating different types of slime involves chemistry and understanding different substances' properties, making it an educational tool for children too.


Slime's invention and evolution have led to a fun and unique toy beloved by many people worldwide. From its origin as a simple toy contained in a plastic trash can, slime has evolved into a vast array of colors, textures, and fragrances. Its popularity continues to grow, making it an icon of toy culture and stress relief.

How Was Slime Invented?

Slime, a gooey and stretchy substance that kids love to play with, has become one of the most popular toys in recent years. However, the history of slime goes back a long time. In fact, slime has been around for centuries.

The first time slime was used as a toy was in the 1970s when Mattel introduced the product "Slime" as part of their toy line. The original slime was made from guar gum, which is an extract from guar beans, and water. It was marketed as a toy that kids could use to play pranks on their friends and family.

Over time, slime has evolved and there are now countless variations of the recipe. The most common recipe for slime is made with glue, water, and borax or contact lens solution. However, some variations include the addition of shaving cream, food coloring, or glitter.

But where did the idea of making slime come from?

The Origins of Slime

It is unclear who first discovered how to make slime. However, the earliest record of a similar substance was found in ancient Greece. The Greeks used a substance called "mucus" as a cleaning agent. Mucus was made from the slime of snails and was used to clean wool before it was dyed.

In the Middle Ages, people used a substance called "ectoplasm" as a spiritual medium during seances. Ectoplasm was made from a combination of water and various substances, such as milk and egg whites, and was used to create a ghostly appearance. Although ectoplasm was not the same as the slime we know today, it is interesting to note that the concept of a gooey and stretchy substance was already being explored.

In the 20th century, slime began to be used as a toy. Mattel introduced the product "Slime" in the 1970s as a reusable toy that kids could use to play pranks on their friends and family. The toy was a hit and other companies soon began to produce their own versions of slime.

Today, slime is more popular than ever. With the rise of social media platforms such as Instagram and YouTube, kids and adults alike are sharing videos of themselves playing with slime. There are even dedicated slime accounts with millions of followers.

How Is Slime Made?

As mentioned earlier, the most common recipe for slime is made with glue, water, and borax or contact lens solution. However, there are countless variations of the recipe.


The basic ingredients for slime are:

  • White school glue
  • Water
  • Borax or contact lens solution

Other ingredients that can be added to customize the slime include:

  • Shaving cream
  • Food coloring
  • Glitter

It is important to note that borax can be toxic if ingested or inhaled. Contact lens solution is a safer alternative, but it is still important to use caution when making slime and to avoid getting the ingredients in your eyes or mouth.

Mixing and Kneading

To make slime, the ingredients are combined in a bowl and mixed together until they form a dough-like consistency. The mixture is then kneaded with the hands until it becomes stretchy and flexible.

If the slime is too sticky, you can add more borax or contact lens solution. If it is too stiff, you can add more water. The amount of each ingredient you need will depend on the recipe you are using.


Slime should be stored in airtight containers to prevent it from drying out. Over time, the slime may lose its stretchiness and become harder, but can be brought back to life with a few sprays of water and some kneading.

In conclusion, slime has a long and interesting history. Although it is unclear who first discovered how to make slime, the earliest record of a similar substance was found in ancient Greece. Today, slime is one of the most popular toys and is enjoyed by children and adults alike.

Manipulating slime is said to help reduce stress levels and increase focus. The act of squeezing, stretching, and squishing the slime helps to relieve anxiety and calm the mind. The texture and aroma of slime can also provide sensory stimulation, which can be beneficial in self-regulation and emotional processing.


Despite its popularity, slime has been subject to controversies related to safety and environmental concerns. Some recipes may contain harmful chemicals that can be harmful if ingested or touched without proper handling. The chemicals used in some slime recipes can cause skin irritation and allergic reactions in some individuals. In addition, improper disposal of the slime may pose risks to the environment due to its non-biodegradable nature. Therefore, slime enthusiasts are encouraged to use safe and eco-friendly ingredients when making and disposing of slime.

In conclusion, slime's popularity shows no signs of slowing down, and it's easy to see why. With its endless possibilities for customization, mesmerizing texture, and stress relief benefits, it appeals to a diverse audience.

How was Slime Invented?

Slime is a sticky, gooey substance that has become increasingly popular in recent years. Many people enjoy the feeling of squishing and stretching slime, and it has even become a popular stress-relief tool. But have you ever wondered how this strange substance was invented? Let's take a closer look at the history and evolution of slime.

The Early Years

The idea of slime as a toy dates back to the mid-1970s, when toy maker Mattel introduced a product called "Slime." This early version of slime was a viscous, green, and rubbery substance that was sold in small plastic trash cans. It was marketed as "ooze for the Alien in You" and quickly became a popular toy among children. In fact, the popularity of Slime was so great that it spawned a whole line of similar products, including "Sludge" and "Muck."However, this early version of slime was quite different from the slime we know and love today. It was made from a blend of guar gum and polyvinyl alcohol, which gave it a rubbery texture and made it difficult to clean up. It also had a strong chemical smell that many people found unpleasant.

The Evolution of Slime

Over time, attempts were made to improve the formula for slime. In the 1990s, a new type of slime called "Gooze" was introduced. This version of slime was made from a combination of water, borax, and glue, which gave it a more pliable texture and made it easier to clean up. Gooze was an instant hit, and soon other companies began producing their own versions of the slime.With the advent of social media platforms like Instagram and YouTube, slime has become more popular than ever. These platforms have allowed people to share their homemade slime creations with the world, and have even sparked a whole subculture of "slimers" who are dedicated to creating and sharing new slime recipes and techniques.Today, there are countless variations of slime, with different textures, colors, and scents. Some people enjoy adding glitter, foam beads, or other materials to their slime to create unique sensory experiences. Slime has become a popular tool for relaxation and stress relief, and is often used in schools and therapy settings for its tactile benefits.

The Controversies and Concerns

While slime may seem like harmless fun, it has been the subject of some controversy and concerns. In recent years, there have been reports of slime toys containing harmful chemicals such as boron, which can cause skin irritation, vomiting, and even seizures if ingested in large quantities. As a result, some countries have banned the sale of certain types of slime.Additionally, slime can be a messy and difficult substance to clean up. Many parents have reported finding dried slime stuck to carpets, furniture, and clothing, leading to frustration and extra cleaning tasks.


Slime has come a long way since its early beginnings as a toy. Its evolution has been driven by a desire to improve its texture and clean-up properties, as well as by the creative ideas of slime enthusiasts. Today, slime is a popular trend enjoyed by people of all ages, and its tactile and stress-relieving benefits continue to make it a go-to substance for many. While there have been controversies and concerns surrounding the safety of some types of slime, with proper care and attention, slime can be a fun and satisfying sensory experience.
