What is the Guinness World Record recognized for the art installation created by school-children?

The Guinness World Record recognized for the art installation created by school children is for having the most artists working on the same art installation. This record highlights a collaborative effort among a large group of children, showcasing their creativity and teamwork in a single artistic endeavor. By working together, these young artists not only contributed to a unique creation but also engaged in a meaningful experience that celebrates both art and community. This record emphasizes the value of participation and the power of collective creativity, which resonates well with educational initiatives involving art. The other options, while potentially interesting, do not focus specifically on the collaborative aspect that makes the record for the most artists particularly significant in the context of school children.
