(Polski) We love creating play spaces in kindergartens, especially those with beautiful gardens. This time we have integrated some of our devices for experiments in the garden of kindergarten No. 148 in Poznań. We made sure that the devices harmonized nicely with the space without overwhelming it, and the whole area looked more like a secret garden of experiences than a playground. Thanks to our scientific play devices, children can experiment with optical illusions (optical wheel, whose face it is) check how a time-lapse animation is created, play a chinese whispers and observe the surrounding nature with a periscope. The benches, beautiful vegetation and peace of the garden allow children to rest in the shade of trees.
