The guys start off by testing some of the mythical properties of Pykrete - is it really bullet proof? Is it really tougher than concrete and does it really melt much slower than regular ice? But then there’s no escaping it - they are going to have to build the world’s first pykrete boat, put it out to sea in Alaska and put their lives on the line. Will they sink or swim? Meanwhile in Snowplow Split, Kari, Tory and Grant split up! Well, not literally but they’re testing a spectacular myth that’s all about bifurcation. The story goes that one dark, wintry night in the frozen north, an old fashioned V-shaped snowplow was busy cleaning the roads. As the snow got heavier, visibility got worse and worse. So bad that the plow driver pulled over onto the side of the road. But moments later, kkerrrassshhhh! The mother of all head long collisions. A car heading in the opposite direction had skidded on the ice and ploughed headlong into the plough. And it’s then that something incredible happened: The car was not a mangled mess, instead it had been split completely in two from bumper to fender. And what’s more - both car driver and passenger were completely unscathed but in two separate halves of the vehicle!
But is this really possible? The guys plan to head to Alaska but in a strange curveball end up in Wisconsin to put this snowy saga to the test. They drive some snowplows, assess their speeds, see the carnage they can cause and then go for it full scale. With front engine cars and rear engine cars towed headlong into a snowplough with a freshly sharpened V, it’s the myth put to the ultimate test.
