Birth & up. This set of six reflective mirror balls all look identical, but have individual characteristics. Some wobble when rolled, or turn and won't roll in a straight line, some feel funny when twisted, spun or shaken and others make different shaker or rattle sounds. The shiny mirror surface provides a distorted fish-eye lens reflection which is fascinating for children to observe. They are robustly constructed from hard wearing stainless steel, are lightweight, smooth and tactile to handle and can be of particular appeal to children with special needs, or for those requiring inspiration in creative language. Each ball approximately 4" in diameter.
The Mystery Sensory Balls are constructed from hard wearing stainless steel so they will not rust. While the balls may be used indoors or outdoors, they are not recommended for use on hard paved or concrete surfaces, which may scratch or weaken the mirrored surface area. The stainless steel surface may be cleaned with a vinegar/water solution or a mild detergent.
