Toy putty, also known as silly putty, is a type of non-Newtonian fluid that has become a popular children's toy. It was first created during World War II as a substitute for rubber, but it was later marketed as a toy due to its unique properties. Toy putty is made from a combination of silicone oil and boric acid, which creates a polymer that has both liquid and solid properties. One of the most interesting properties of toy putty is its ability to bounce like a ball when it is rolled into a ball and thrown. This is because the putty is able to absorb and transfer energy, which allows it to bounce back. Additionally, toy putty can be stretched and molded into different shapes, and it will retain its shape until it is manipulated again. Toy putty is also known for its unique texture. It is soft and pliable, but it can also be firm and rigid when it is compressed or molded. This texture makes it a popular sensory toy for children with autism or sensory processing disorders, as it provides a tactile experience that can be calming and soothing. While toy putty is generally considered safe, it is important to note that it should not be ingested. Additionally, it can leave residue on surfaces, so it should be kept away from carpets and fabrics.

Toy putty, also known as silly putty, is a type of non-Newtonian fluid that exhibits both liquid and solid properties. It was originally created during World War II as a substitute for rubber, but it quickly gained popularity as a children's toy due to its unique properties. Toy putty is made from a silicone polymer that is mixed with boric acid, which acts as a cross-linking agent. The resulting material is a viscous, stretchy substance that can be molded and shaped like clay. One of the most fascinating properties of toy putty is its ability to bounce like a ball when rolled into a sphere. This is due to its high elasticity, which allows it to deform and then spring back into shape when subjected to a force. Toy putty also has a low melting point, which means that it can be easily molded and shaped by hand. Additionally, it can be stretched and pulled into thin strands, making it a popular sensory toy for children with autism or ADHD. Toy putty comes in a variety of colors and can be purchased in small containers or in larger quantities. It is often sold in egg-shaped containers or in plastic eggs, which adds to its appeal as a novelty toy. While it is generally considered safe for children to play with, it should not be ingested as it can cause digestive issues.
