The Object Permanence Box with Tray teaches the Child object permanence and develops hand-eye coordination.
The Object Permanence Box & Tray guides the Child to insert the ball through the hole at the top of the box.
The ball vanishes out of sight and reappears in the tray, rolling in and out of the box. This gives a lesson in object permanence, showing the child that although the ball is out of sight, it has not vanished.
