Q: How does the silent basketball work? A: The silent basketball is made of high-quality PU Foam, comfortable in your hands, very elastic, super soft, and easy to grip. Lighter than a normal regulation basketball, it's designed to be soft and quiet, producing no sound during use. Q: Does the silent basketball need air? No need to inflate! After being physically foamed, it undergoes a special process to ensure elasticity, resulting in inflated holes to maintain its shape. The silent basketball utilizes foam materials to absorb impact, reducing the noise associated with a regular bouncing basketball. Q: Can you use the silent basketball on carpet? Absolutely! The ball bounces well on carpet and rugs, making it perfect for indoor training, especially for kids. Some users note that the surface can be slightly slippery, posing a challenge for dribbling.
