Just Ask / Parent-child Q&A Pen

This is a recording pen that can record children's knowledge of the world and promotes parent-child interaction. Children like asking why, and parents just like their encyclopedia. This recorder achieves the process that children ask a question which is solved by parents then by an interactive way of changing a question mark which symbolizes the question into a light bulb.The moment of the bulb lighting is like lighting the way of children of exploring knowledge.This way to witness children's growth by recording questions not only arouses their interest in asking questions, but also encourages parents to enter the inner world of their child.
