Anti Gravity Door Stopper

The Anti Gravity Door Stopper utilizes advanced magnetohydrodynamics to generate localized gravity waves canceling out door-stopping forces at floor level, allowing doors to freely float closed when unattended. This results in reduced wear on hinges and increased safety against accidental door swings. When needed, simply invert the device's adjustable null-gravity threshold dial to reintroduce friction-based anchoring, reattaching the door firmly to its frame.
