Rock shop that ships to Europe (Croatia)?
By 1a2b | May 14, 2012
I can’t seem to find the shop with rock/punk clothes on the Internet, so I would appreciate your help. Please, no gothic sites. It’s also important that the shop ships their clothes to Europe, because I live in Croatia.

Carbon atoms on surface of diamond unsaturated?
By 1a2b | May 12, 2012
In a fit of largesse I bought four sets of organic chemistry model pieces (molymod), confident that I had overcome the only thing that prevented me from modeling the structures of diamond and graphite for my kids’ class at the local lapidary society–i.e., not enough four-hole carbon atoms.
Sadly, my ignorance seems to be a barrier, too!
After four hours I proudly presented my completed diamond model to my daughter, who said, “Um, Mom, shouldn’t it be an octahedron?” “It IS an octahedron!” I protested, until I counted the sides. Nope, I’d somehow managed to construct a TETRAHEDRON. I had to start over (daughter’s hands aren’t strong enough to snap the pieces together, or I’d have her do it).
I now have an octahedron…but I won’t show it to my kids for fear that they’ll ask me, “Why do all the carbons on the outside of the diamond still have one hole left over?” Because I dunno.
So, are those surface atoms double-bonded, or bonded to junk on the surface, or ?
