Samu, 7, and his Aalto University Junior summer camp friends crafted lovely dollhouse furniture, decorations, and characters for Aalto University exhibition, Designs for a Cooler Planet. The best part? Everything is made from biodegradable – and often everyday – materials, like orange peel and paper. 🍊 'We craft stuff out of biodegradable materials, because if you throw them in nature, then they won't do anything bad for it,' Samu says. We absolutely love these creative material experiments by
