Fantastic to explore science, maths and art. Children can control how gravity creates unique sand patterns and explore the effects of forces. It provides moments of awe and wonder, as children create amazing geometric, sand patterns and provides opportunities to spot shapes within shapes! Using dry sand, the bucket can be swung at different angles and speeds, inspiring unlimited creativity.
