Gyroscopically Stabilized Rail Runner: this toy remains upright on a single wheel as it travels along any thin rail or tightrope. A flywheel with considerable mass is ramped up to high RPMs via a small motor powered by two AA batteries (a stand is provided for this initial process to complete). Once operating speed is obtained the device will keep its orientation due to conservation of angular momentum, allowing it to seemingly magically balance on one point. The motor also turns the drive wheel
