The Ultimate Recycling Machine is back at Pretend City! This large scale hands-on experience geared towards school-aged children combines engineering, collaboration, and sustainability. The challenge is to design and build a machine, “the Ultimate Recycling Invention” that transports a plastic bottle into a recycling bin. It always looks different, with combinations of tube structures, zip lines, pulleys, pendulums, and more. This new activity is ideal for intergenerational participation – grown-ups and children alike will be fully engages. You will be amazed by how much creativity, tenacity and teamwork emerges from this simple set-up!
