KSIT032 - Ellipsoids On Small Pegs
A square wooden board with 4 pegs that holds 4 ellipsoids of the same size. Placing the ellipsoids on the pegs is a challenging task for the infant.
As the pegs seem to disappear in the ellipsoids, the child experiences that the centre hole in the ellipsoid disappears too, and the shape becomes whole.
