A jewelry display includes a ferromagnetic planar substrate and a bracket configured to be attached to a wall. The bracket has at least one wall engagement surface disposed along an inner surface and at least one ferromagnetic planar substrate engagement surface disposed along an outer surface. An adhesive backed non-slip covering adhesively attaches to the substrate engagement surface. At least one bracket magnet is disposed on the inner surface of the bracket. A plurality of jewelry fixtures are configured to be removably attached to the front surface of the ferromagnetic planar substrate, each jewelry fixture having at least one permanent fixture magnet and a jewelry holding structure, where the at least one permanent fixture magnet of each jewelry fixture is magnetically attracted to the ferromagnetic planar substrate.

A vehicle configured to move through a network of interconnected tubes includes a body, a motor, a motorized wheel, a biasing assembly, and a first element. The motorized wheel directly engages an inner surface of the tubes. The biasing assembly causes the motorized wheel to maintain continuous contact with the inner surface of the tubes during operation. A waist of the vehicle is constrained by an inner diameter (D) of the curved tube, a radius of curvature (R) of the curved tube, and a length (L) of the wheelbase of the vehicle. The waist of the body is sized such that the vehicle can freely move within any of the tubes without getting stuck therein.

A jewelry display includes a ferromagnetic planar substrate having a front surface opposite a back surface. A bracket is configured to be attached to a wall, the bracket comprising at least one bracket magnet which is a permanent magnet. The back surface of the ferromagnetic planar substrate is configured to removably attach to the bracket due to the magnetic force of the at least one bracket magnet. A plurality of jewelry fixtures are configured to be removably attached to the front surface of the ferromagnetic planar substrate. Each jewelry fixture includes at least one permanent fixture magnet and a jewelry holding structure. The at least one permanent fixture magnet of each jewelry fixture is magnetically attracted to the ferromagnetic planar substrate. The at least one bracket magnet may be at least 2, 5, 10 times or more as powerful as the at least one permanent fixture magnet.

A track for a toy vehicle includes several track units. Each track unit has an upper layer and a spaced apart lower layer. Each of the adjacent units comprises two sections. A first section has an upper side for supporting the toy vehicle and a bottom side. A second section has an upper layer having a top side for supporting the toy vehicle and a lower base. The first section has a first connector, and the second section has a mating second connector. The first and second connectors are connectable so that first and second sections are connectable in an adjacent unit to form an adjacency relationship. Each unit includes a first section and two second sections. Two second sections are located at opposite longitudinal ends of the first section. The first section is bendable in a longitudinal sense substantially parallel to a plane on which a track is directed from one end to the other end in a track running direction. The second section is bendable in a transverse sense substantially transverse to a plane on which a track is directed from one end to the other end in a track running direction.

An exhaust system for a combustion engine vehicle includes an exhaust pipe extending between an exhaust inlet disposed opposite an exhaust outlet. The exhaust inlet and exhaust outlet are in fluidic communication with one another. The exhaust inlet is configured to receive an exhaust gas produced by an internal combustion engine of the combustion engine vehicle. A second pipe has an air inlet extending from and connected to the exhaust pipe. The second pipe is configured to be in fluidic communication with the exhaust outlet. The air inlet is configured to receive an outside flow of air. The exhaust gas from the combustion engine vehicle and the outside flow of air captured by the air inlet when the combustion engine vehicle is moving forward are configured to be combined and to cooperatively exit out the exhaust outlet.
