Bubble icosahedron of flexible dodecahedra @EdoTimmermans

Uploaded July 2013 | Updated September 2026, 1 week ago

This construction is an improvement on my previous build 'Icosahedron of dodecahedra'. The unit now looks like an almost perfect dodecahedron except for the corners being a bit flat, also putting 12 of them together in icosahedron formation (when you connect the centers of the 12 dodecahedra, you get an icosahedron) can be done much better due to the units being both quite strong and very flexible.
Of course, the 12 units can also be seen as the corners of an icosahedron.

$Sierpinski octahedron & more The Sierpinski ocgtahedron is a 3D fractal. I remember seeing Sierpinski cubes and tetrahedra made with magnets, but not the octahedron. My build only is the second iteration, with smaller octahedra a third iteration should be possible to make. The other builds in this video, made with the same octahedra: a dodecahedron and a tetrahedron.$
