Toy

Claim 1

Toy, comprising: (a) a coil of copper tape of high width-to-thickness ratio which has a degree of plasticity such that, when the center of the coil has first been pressed expanded in a first direction, forms an elongated frusto-conical structure that, when later pressed axially in the other direction and quickly released, exhibits spring characteristics combined with damping characteristics by virtue of sliding action between the adjacent layers, wherein the spring characteristics are in accordance with Hook's Law and the damping characteristics are of the Coulomb friction type, so that the spring element, after being released, exhibits alternating reversal of movement for an observable period of time, and (b) a package consisting of a base and a frusto-conical cap, wherein the coil normally rests in the base and the cap has a lower portion fittingly around an upper edge of the base, so that, when the cap is removed from the base, the coil expands outwardly and exhibits the spring characteristics, wherein the copper is soft in nature, wherein the length of the tape in the coil is in the range from 50 inches to 58 inches, the width is in the range from 0.75 inches to 1.00 inches, and the thickness is in the range from 0.003 inches to 0.005 inches.
