Pronunciation: [flˈʌbə] (IPA) 
The word "flubber" is spelt with a double "b" because it represents a voiced bilabial plosive at the end of the word - /bəl/. The IPA phonetic transcription symbol for this sound is /b/. Flubber is a type of green gooey substance. It was first introduced in the 1961 film "The Absent-Minded Professor" and is also featured in the 1997 remake, "Flubber", starring Robin Williams. Flubber has since become a popular toy among children.
Flubber is a noun that refers to a type of gelatinous, stretchy, and bouncy material or substance. It is commonly used in children's toys, educational materials, and science experiments. Flubber is a non-Newtonian fluid, which means it does not typically follow the rules of classical fluid behavior.
This term gained popularity and recognition primarily through the 1961 Disney film "The Absent-Minded Professor" and its subsequent adaptions, as well as the 1997 remake titled "Flubber." In the movie, the protagonist invents a green, rubbery substance called "flubber" that possesses remarkable properties, such as high elasticity, the ability to levitate, and incredibly convulsive motion.
In real-life applications, flubber-like substances are often created by mixing glue, water, and borax, resulting in a slimy and malleable material. The addition of food coloring can provide various colors to flubber. It has become a popular do-it-yourself experiment, science project, or therapeutic stress-reliever for children and adults alike.
Due to its unique characteristics, flubber is often employed as an engaging tool for tactile and sensory experiences, promoting creativity and scientific exploration. Furthermore, its pliable qualities make it an enjoyable substance for molding, stretching, and squeezing, providing both entertainment and educational value for children's playtime and scientific investigations.
The word "flubber" was coined and popularized by the American inventor and animator Walt Disney in the 1961 film "The Absent-Minded Professor". In the movie, a scientist creates a bouncy, rubber-like substance and names it "flubber". The term likely derives from the combination of the words "flying" and "rubber", as flubber has the ability to make objects defy gravity. The term "flubber" has since become synonymous with a fictional, energetic, and bouncy material in popular culture.
