Juggling balls are specially designed spheres used in the art of juggling. They are typically made from soft materials like rubber or fabric, which makes them easy to catch and throw. Juggling balls come in various sizes and weights, allowing jugglers to choose the ones that best suit their skill level and preferences. These balls are often filled with materials like sand or beads to provide stability and control during juggling. Many jugglers also use juggling clubs or rings as alternatives to balls, but juggling balls remain the most popular choice for beginners due to their forgiving nature and ease of use.
