The Saimiri Trail’s WOW factor is its transparent, hugely varied range of difficulty levels in climb, crawl, spin, rotate, sway and balance activities. These activities help develop children's agility, balance and coordination, motor skills that are fundamental for a range of important life skills. Eventually, this supports a secure and confident navigation of the body. The fun loop of varied activities supports classic games, e.g. “the ground is made of lava”, which pump up the heartrate and encourage cooperation. The possibility to communicate across the play unit and take breaks at several destinations supports turn-taking and communication, important social-emotional skills that are supported in play. The Musca Spinner offers a solitary spinning point at hilarious speed, where children use all body muscles to push and pull themselves into fast rotation. This supports empathy and cooperation, and not least an incorporated understanding of gravity.
