Flubber |best| Jun 2026

In the film’s logic, Flubber is a stable polymer with the unique ability to absorb and amplify kinetic energy. If you drop it, it bounces back higher than the point from which it fell. It defies entropy.

Ironically, while Disney’s Flubber is impossible, a substance widely sold and known as "Flubber" exists in every elementary school science classroom. This is not a flying rubber, but a non-Newtonian polymer slime. Flubber

Technology, no matter how "miraculous," cannot replace the people—or the moments—we lose while we're busy tinkering with it. Lessons from the Goo Elasticity of Spirit: moral of Flubber persistence and bouncing back In the film’s logic, Flubber is a stable

In the real world, "Flubber" is a staple of STEM education. It is classified as a or a gel, exhibiting properties of both solids and liquids. Educators use it to demonstrate cross-linking in polymers. Taylor & Francis Online Lessons from the Goo Elasticity of Spirit: moral

| Material | Coefficient of Restitution (elasticity) | Stability | |----------|-------------------------------------------|------------| | | >1.0 (violates thermodynamics) | None | | Superball (polybutadiene) | ~0.85 | High | | Steel ball bearing | ~0.6 | Very high | | Flubber (real slime – borax+PVA) | ~0.2 | High (non-energetic) |
