Abstract
Quantum superposition is one of the most challenging concepts in introductory quantum physics. This paper proposes a simple "blended cat"classroom demonstration designed to support the teaching of quantum superposition. The model consists of a double-sided rotating plate displaying two mutually exclusive states. When spun, the images appear visually blended; when stopped, a single state is observed. The demonstration is not intended as a physical representation of a quantum system but as a conceptual tool to initiate discussion about the meaning of superposition and measurement. Through guided questioning, students are encouraged to reflect on what it means for a system to be in a superposed state and how measurement determines observable outcomes. The activity provides an accessible and engaging entry point for introducing quantum superposition in secondary and introductory university physics courses.
