How cool is this Luciteria web site? Well if you are a geek like me, very cool indeed. Among other things they sell are cubes of each of the elements in the periodic table. As they say:
Cubes of each of the elements are our most popular sellers. And it’s not hard to see why. Precision machined and labeled each one is a self-contained ambassador of the periodic table. From the small cubic centimeter up to the hefty 5cm these cubes practically define the ideal desktop gadget for anyone who loves to nerd out on science. So get one as a conversation starter, a few as a clever means to spell out a name or phrase or go for broke and get as many as possible to make your own “real life” periodic table!
Some of them, like copper above, are pretty harmless and common. Others, like the uranium cube below, not so much.
I think these would be a great gift for anyone into science, or for teachers teaching the elements.
My first thought when I went there was that they would only have a few of the elements, but no, they have pretty much all of them. (With some reasonable exceptions.) Very much worth checking out.
