I present to you five intersecting tetrahedra, carved from a single piece of Elm wood by my tiniest tools. This is a project described in the excellent book 'Magic Woodcarving' by Bjarne Jespersen, although he only presents a prototype made from dowels in the book, going on to produce an inverted version as well.
Geometrically, each of the five tetrahedra sit on the 20 vertices of a dodecahedron, and as you can see in the video I started from this polyhedron for my carving. I go on to define each edge with a saw cut, and then chisel back to reveal each point of the tetrahedra. Eventually, the centre can be hollowed out and all of the sections separated from each other.
I hope you enjoy this, and I may post more of my creations if there is any interest! Feel free to ask any questions - I am always happy to talk to people who share my enthusiasm for woodworking.

I had an idea for a centrifugal gun that fired Meissner Tetrahedra rather than the usual ball ammunition to save space, and I was wondering how well these projectiles would actually work. Thanks to whoever answers this.
Borosulfates are classified as silicate analogue materials. The number of crystallographically characterized compounds is still limited, whereas the structural diversity is already impressive. The anionic substructures of borosulfates exhibit vertex connected (BO 4 )- and (SO 4 )-tetrahedra, whereas bridging between two (SO 4 )- or even between two (BO 4 )-tetrahedra is scarce. The herein presented compound Sr[B 3 O(SO 4 ) 4 (SO 4 H)] is the first borosulfate with a triple vertex linkage of three (BO 4 )-tetrahedra via one common oxygen atom. DFT calculations complement the experimental studies. Bader charges (calculated for all atoms) as well as charge density calculations give hint to the electron distribution within the anionic substructure and DOS calculations support the interpretation of the bonding situation.
