These sensory balls are a real learning experience! Durable and made of stainless steel. The 6 reflective mirror balls look identical, but each has individual properties and behaves differently. They can spin around when rolled, while others don't want to roll at all. Two of the balls are quiet, but not one of them will roll in a straight line. The feel of the balls when shaking, rolling or even dropping them is so different. The hand-polished, shiny mirror surface creates an optical illusion, the reflection will fascinate children and encourage them to observe. They are durable, light, smooth, and tactile. By working with these balls, children will learn and discover so many new things, experience miracles, and get to know each of the balls, they will roll, shake, and reflect! No wonder these balls are popular in the Montessori method - they are the same, but so different, without defined rules of the game, the child can freely explore and experiment. Relevant for all ages!
