rubber ball
The bounciest balls are the so-called bouncy balls, made of compressed synthetic rubber. These balls have an unusually high coefficient of restitution (inverse momentum) that allows them to return to up to 92% of a dropped height, and to utilize thrown force to reach extraordinary heights. Another generic name for the balls is "super balls," originally a trademark name for a 1964 invention first sold by the Wham-O toy company in 1966.
you want a soft rubber band ball with strechy rubber bands,but you also want to be carefull that you dont make it to big and to small
Generally the core of the ball is cork, rubber, or a mixture of the two.

The physics equation used to calculate the trajectory of a bouncing ball is the coefficient of restitution formula, which is given by the equation: v2 e v1, where v1 is the initial velocity of the ball before it bounces, v2 is the velocity of the ball after it bounces, and e is the coefficient of restitution that represents the elasticity of the collision.
The coefficient of restitution is how you quantify bounciness or give bounciness a number, and you do that by dividing the bounce height by the drop height, then finding the square root of that. When you have more bounces you can find more than one coefficient of restitution!
Different balls have different things inside them. Some modern golf blls are massive polyurethane. A tennis ball, foot ball and soccer ball has air under pressure. a ingpong ball relies on the coefficient of restitution of the plastic (and the trapped air inside). Generally a material that can be deformed and regain its shape quickly (a high coefficient of restitution).
The coefficient of restitution for a perfectly plastic body is zero. This means that the body will not bounce off or rebound after impact, but will instead stick together with the other body.
The coefficient of restitution is a measure of how much energy is retained during a collision. A higher coefficient of restitution means more energy is retained, resulting in a higher bounce height for an object.

Any ball with sufficiently low coefficient of restitution will not bounce (a ball of clay or putty for example.
No, BBCOR bats are required for high school baseball. BBCOR stands for "Batted Ball Coefficient of Restitution."
With a plastic impact, the coeffecient of restitution is 0. With an elastic impact, the coeffecient of restitution is 0<e<1. With an inelastic impact, the coeffecient of restitution is 1.
