Redefine gravity and challenge your friends with the Aerobie Sonic Bounce balls for kids! Engineered with the intention to be the highest bounce ever, the Sonic Bounce is built with high density foam material, using geodesic geometry and scientific construction to provide super high bounces! The spikes on the ball act as conduits for kinetic energy, providing more rebound and resulting in a higher bounce as compared to traditional sphere-shaped outdoor play balls. The tactile grip paired with size and shape of the Sonic Bounce makes it easier to catch, throw and bounce, for more fun when challenging your friends or improving hand-eye coordination when playing alone. Get together with friends and challenge each other to see who has the highest bounce or compete in a tournament of the coolest trick shots! These bouncy balls are 2.6" in diameter for an easy carry or great to slip into backpacks or goody bags as party favors for kids. The tactile grip makes the Sonic Bounce fun to hold and great for bounce ball enthusiasts of all ages. The Sonic Bounce balls are also perfect goodie bag stuffers and outdoor toys for kids and teens! Challenge your friends to see who can bounce the highest or perform the coolest trick shot with the Aerobie Sonic Bounce! Ages 8+
