Quantum Superposition Is Hard To Explain (Physics) Tea Towel

No need to be a physicist to under the concept of quantum superposition, the fundamental law of quantum mechanics that defines the collection of all possible states that an object can have. Includes Schrödinger's cat and the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. Make others do a double-take when you try to explain how hard it is to explain quantum superposition with any of these geek humour gifts!
