For this is a device that, although not possessing perpetual motion or gravity-defying properties, does nonetheless momentarily challenge that premise. If you catch one's drift.
In short, this is a nifty self-assembly magnetic rollercoaster that mixes drops, jumps, stunts and loops (to use 'coaster lingo) with one's very own DJ choons. It's a fusion of sight, sound and speed with extreme G-force, 21st century design and some rather splendid physics thrown in for good measure. So pump up the volume and crank up the speed, daddy-o.
