The bounciness of the playground ball made it hard to catch.

Different materials on the playground exhibit varying bouncinesses, which affect how high the children can jump.

They giggled and whispered before slipping away for a little bouncy-bouncy.

The bouncy playground ball flew over the fence when she kicked it.

She packed three bouncy balls into her bag before going to the park.

The children spent the afternoon laughing and tumbling in the bright red bouncy castle.

The festival rented several bouncy castles to keep the children entertained all afternoon.

The toddler giggled as the bright red bouncy ball bounced twice against the pavement and rolled away.
