Material
Bouncy balls are mainly comprised of silicon and sulfur compressed at 1,200 PSI. They can retain 80 percent of their kinetic energy, which is why they are so bouncy.
Bouncy Ball Beginings
Bouncy balls were introduced to the public by way of the bubble gum machine, and sold for 25 cents per ball.
Styles
Bouncy ball designs have evolved from simple solid colors to complex designs like tie-dye, streaks, see-through, sparkles and neon. Novelty styles are also common, such as eye balls, billiard balls, happy faces and sports balls.
Sources
Bouncy ball enthusiasts can find arrays of bouncy balls at toy stores, grocery stores and even restaurants. There are also online retailers that sell specialty bouncy balls (see Resources).
Warning
Bouncy balls come in various sizes and colors, and are often mistaken by young children for sweet treats like gum balls and jaw breakers, which can lead to accidental ingestion. This is why bouncy balls are advised for children ages three and up.
