| Kenneth Kawamura's butterfly ball is a deceptive action model. Assembled from twelve water bomb bases, it forms a complex and pleasing geometric shape known as a cubohemioctahedron (a cuboctahedron with tetrahedral cavities). The assembly is stable when resting on a surface. However toss it in the air and give it a light smack to see it explode into a cloud of butterflies which flutter prettily to earth. For this reason, it is also referred to as a butterfly bomb. | |
