A team of students from Eindhoven University are to build a forty metre high model of Antonio Gaudí's Sagrada Familia. The project, which follows the completion of the world's biggest ice dome last year, will be constructed from pykrete and reinforced with wood fibres. Impressively, the 1:4 scale model will be built in only three weeks. Thin layers of water and snow will be sprayed onto large, inflated molds. The pykrete (water mixed with sawdust) will be immediately absorbed by the snow before freezing. According to the organisers, "the wood fiber content makes the material three times as strong as normal ice, and it’s also a lot tougher." Find out more about the project here.
