In geometry, a near-miss Johnson solid is a strictly convex polyhedron whose faces are close to being regular polygons but some or all of which are not precisely regular. Thus, it fails to meet the definition of a Johnson solid, a polyhedron whose faces are all regular, though it "can often be physically constructed without noticing the discrepancy" between its regular and irregular faces. The precise number of near-misses depends on how closely the faces of such a polyhedron are required to approximate regular polygons. Some near-misses with high symmetry are also symmetrohedra with some truly regular polygon faces. Some near-misses are also zonohedra. (Wikipedia).

Pykrete Made From Toilet Paper Crushed By Hydraulic Press
In this video I crush toilet paper pykrete with a hydraulic press. The pykrete is extremely strong and is very difficult to crush in the hydraulic press. Pykrete is a mixture of sawdust or wood pulp with water. After it is frozen it forms a substance that is about as strong as concrete! It
