A superball or power ball is a bouncy ball composed of a type of synthetic rubber (originally a hard elastomer polybutadiene alloy named Zectron) invented in 1964, which has a higher coefficient of restitution (0.92) than older balls such as the Spaldeen so that when dropped from a moderate height onto a level hard surface, it will bounce nearly all the way back up.
The vibraslap is a percussion instrument consisting of a piece of stiff wire (bent into a U-shape) connecting a wooden ball to a hollow box of wood with metal "teeth" inside. The percussionist holds the metal wire in one hand and strikes the ball (usually against the palm of their other hand).
A Super Ball or Superball is a toy bouncy ball based on a type of synthetic rubber invented in 1964 by chemist Norman Stingley. It is an extremely elastic ball made of Zectron, [ 1 ] which contains the synthetic polymer polybutadiene as well as hydrated silica , zinc oxide , stearic acid , and other ingredients. [ 2 ]
The toy is formed out of two solid balls of polymer, each about 2 inches (5 cm) in diameter, attached to a finger tab with a sturdy string. The player holds the tab with the balls hanging below and through up-and-down hand motion makes the two balls swing apart and back together, making the clacking noise that gives the toy its name.
The bounce of an oval-shaped ball (such as those used in gridiron football or rugby football) is in general much less predictable than the bounce of a spherical ball. Depending on the ball's alignment at impact, the normal force can act ahead or behind the centre of mass of the ball, and friction from the ground will depend on the alignment of ...

A noisemaker is something intended to make a loud noise, usually for fun. Instruments or devices commonly considered "noisemakers" include: pea whistles; air horns, composed of a pressurized air source coupled to a horn, designed to create an extremely loud noise; fireworks, such as firecrackers, bottle rockets, bang snaps and others
1. Bop-It. Bop-It has a lot of things going on for the listener that are pretty close to insufferable. For starters, every sound effect this game makes is cartoonish and insane.
