An elongated substantially hollow body supports a pair of motor drive units, a battery power supply, and a radio frequency receiver and controller module. A pair of axles are rotatably supported near the frontal end of the elongated body and in turn support a pair of large diameter wheels. The motor drive units within the body are operatively coupled to the axles and are able to differentially drive the wheels. The position of the axles and wheels near the frontal portion of the vehicle results in the extension of a substantially greater portion of the body away from and beyond the wheels. Thus the extending portion of the body defines a trailing end. A control transmitter provides independent operational signals to each of the motor drive units to differentially drive the wheels. Each time the direction of travel of the toy vehicle is reversed, the reaction torque applied by the motors to the body causes the body to flip about the axles and invert bringing the trailing end to the opposite side of the wheels. By skillful manipulation of the controls, various tricks and stunts may be performed by the toy vehicle. The toy vehicle is also operable in an aquatic environment utilizing the wheels as paddle wheels for propulsion.

An air-powered projectile launcher includes a housing defining a cylindrical launch tube for receiving a projectile and a cylindrical cylinder bore. A piston having an extending piston rod is sealingly movable within the cylinder bore and is coupled at its forward end to a coil spring. The piston rod extends rearwardly through a trigger and cocking mechanism which in turn is coupled to a pivotal pump handle. A ratcheting mechanism is operatively coupled between the pivoting pump handle and the piston rod to facilitate the incremental drawing motion of the piston rod and piston stretching the power spring. The trigger mechanism holds the piston rod against the force of the stretched spring until the user pulls the trigger into its release position. Thereafter, the stored energy of the spring drives the piston forward against the launch tube and projectile providing an air burst which launches the projectile.

A key holder which has a pair of shells for enclosing the keys which are connected together by a spring-loaded locking hinge. The keys are connected to the shells by at least one arm attached to one of the shells. The keys can be stacked on top of each other inside the key holder. The spring-loaded locking hinge generally holds the shells in a closed position relative to each other. This is accomplished by a knob on one part of the hinge which engages with a notch on another part inside the hinge. A spring kept in torsion and compression tends to urge the shells open so that when a button on the end of the hinge is pressed, the knob disengages the notch and the spring causes the shells to open.
