The Imanix Slide 70-Piece Magnetic Construction Set by Braintoys (BT.350070) is a set of 70 translucent and colorful magnetic pieces, including 4 balls to slide along slides and ramps built by the child. Each piece has magnets integrated into its edges that allow connecting geometric blocks of different sizes, colors, and curves, enabling 2D and 3D constructions where the ball travels along the assembled path. It is made entirely of non-toxic plastic, and the translucent pieces make this set especially interesting for playing on a light table, exploring the passage of light through the constructions. By planning and testing different paths for the ball, the child develops eye-hand coordination, concentration, and creativity, as well as exploring basic notions of mathematics, science, and engineering in a playful way. It is suitable for children from 3 years old and is compatible with other sets in the Imanix range to expand constructions and create even larger circuits.
