For those of us stuck at home, Adventure Ecology is offering another option: Build a toy version. The toy Plastiki is a scale model of the 60 ft. swiss replica watches catamaran. In keeping with de Rothschilds ethos, the model is made from cardboard approved by the Forest Stewardship Council and printed with vegetable inks. The model costs ￡18 (about $30) and half the proceeds go to Sculpt the Future, an organization that promotes environmental action.
