Project habakkuk or habbakuk (a common misspelling) was a plan by the british during the second world war to construct an aircraft carrier out of pykrete (a mixture of wood pulp and ice) for use against german u-boats in the mid-atlantic, which were beyond the flight range of land-based planes at that time.the idea came from geoffrey pyke, who worked for combined operations headquarters.. Pykrete is a frozen composite material, originally made of approximately 14 percent sawdust or some other form of wood pulp (such as paper) and 86 percent ice by weight (6 to 1 by weight). during world war ii, geoffrey pyke proposed it as a candidate material for a supersized aircraft carrier for the british royal navy.pykrete features unusual properties, including a relatively slow melting. Parade ice garden offers premier indoor ice skating to the public year round..
