Steel was in short supply during the height of World War II , and there was nothing to be done but contrive a replacing . One proposal was called Pykrete , a admixture of ice and sawdust that melted improbably slow . The idea faded off once the warfare finish — but now , a mathematical group of Dutch designer and engineers are animate it . In a heavy , big style .
First , a little backstory . Pykrete was created by a British discoverer named Geoffrey Pyke . As io9 explained a few years ago , Pyke was convinced that he had a better alternative to replace sword : A special mixture of about 14 percent sawdust and water . When frozen , this special fluid would form an surprisingly solid hybrid material that did n’t melt and was resistant to shatter .

In fact , the British government activity even debate using it to ramp up an aircraft carrier . But when the war finish , Pyke ’s gewgaw melt out , though it was n’t entirely forgotten ( maybe you sawthis MythBusters episodeabout the stuff ) .
Enter the Eindhoven University of Technology , where students and professors are resurrecting pykrete for use in architecture . Last year , a team build the world ’s turgid Methedrine bean with the material ( mark outan incredible making - of picture here ) .
trope : Joep Rutgers .
Using an inflatable noggin , they were capable to spray enough of the mixture onto its surface to create a loose - stand bean with a 98 - foundation straddle .

Now , the team says they ’re readyto take it to the next level . This meter , they ’re building a 1:4 model of Barcelona ’s famed Sagrada Familia out of pykrete . “ We could have just settle to construct another , even larger , dome , ” said professor Arno Pronk . “ But in building terms the Sagrada Familia is a much bigger challenge . And of course of study it ’s very recognisable . ”

This winter , a team of 50 will get lead off on the projection by creating a inflatable mildew of the museum in northern Finland . Then , they ’ll handle it with snow and blow the water system and sawdust smorgasbord over it — which will freeze and form the mysterious pykrete , which is three time as strong as normal Methedrine .
The project will really get bulge out this September , when temperatures sink in Juuka , one of the frigid station in Europe . Pronk is upset , though : Juuka had one of the warmest wintertime on criminal record last year , which could badly endanger the projection if this wintertime is a repeat . Here ’s hoping for deep frost . [ GizMag ]
