Quantum-Locked Toothpick

This Quantum-locked Toothpick exists at two contradictory states simultaneously – firmly lodged between teeth, yet effortlessly extractable upon concentration alone. Whenever used by someone else, it instantly reorients itself within their mouth to point towards a nearby exit door, encouraging departure. As people familiarize themselves with its presence, the toothpick subtly adjusts taste preferences toward acquired flavors rather than inherent ones.
