Robustly constructed from stainless steel, these 7 reflective mirror balls are graduated in size from 50mm to 110mm, each with different contents so that every ball produces a different sound and movement effect. The hand finished shiny mirror surface provides a distorted fish-eye lens reflection which is fascinating for children to observe. They are lightweight, smooth and tactile to handle and can be of particular appeal to children with SEND, for those requiring inspiration in creative language, and for young scientists to work out why different materials can create different sounds and have different effects on movement. Stainless steel is an ideal material for using in sensory play resources:• Chemical free – no toxins• Durable – strong and lightweight• Hygienic – non-porous and naturally bacteria resistant Supports the following areas of learning: • Personal Development - sensory• Communication & Language - descriptive language• Understanding the World - observation• Understanding the World - sound• Physical Development - hand-eye coordination• Physical Development - motor skills What the Nursery World Awards testers said: Children love looking at their reflections and hearing the different sound effects made by these sensory, shiny balls which are made from stainless steel. Each of the seven mirrored balls comes in a different size and contains objects that produce sounds like soft and loud chimes. Handling them is easy, the testers observed, as they are lightweight, smooth and tactile - and even the bigger balls are manageable for small hands. "It's so much fun to roll them," one setting reported, "because they go off in different directions." Other highlights include "pulling faces" into the mirrored surface, which provides a distorted fish-eye lens reflection.
