PATIKIL Iron Cube, 10mm Fe-Density Cube High Density Element Cube Unique Metal Cube Periodic Table of Elements Collections Lab Experiment Teacher Scientific Classes

Just interesting -- same density as gold (19.2 vs 19.3 g/cm). Weighs about right on my kitchen scale, so I suppose it's the real thing. A 1cc sample does not feel ponderously heavy -- perhaps a 1 cubic inch sample would yield a greater impression (I suppose it would have to, speaking physically). Very sharp corners and edges, labelled on two sides, and comes with a good size plastic box (maybe the box has a purpose: don't put those sharp edges on something they may scratch, and don't drop it on a hardwood floor, or a toe -- very sharp).

Absurdly heavy! Highly recommend!

It came on looking shiny with no blemish.

My son likes it

Corner of the cube was chipped off. On pretty much all sides.

Molto curato ma davvero minuscolo.

Niobio es uno más de mi colección de merales

Es pequeñito pero tengo una buena colección de cubos de metal.

Bon cube de 10mm de côté.

If you're building a collection of elements, it would be rude to omit Niobium. Relatively not-all-that-toxic to handle, this is a nice 1cm cube you can hold, poke at, weigh and admire alongside other metallic and solid elements. Reasonably educational, nice to have. Even though they're pretty small, these 1cm cubed samples do provide a visceral impression of the relative densities, just held in the hand. A sample of Tungsten, for example, is clearly *way* more dense than a chunk of Magnesium or Aluminium. If you wondered what Niobium looks like, and how heavy it seems compared to stuff like aluminium and iron, thios is a fairly accurate 1cc of the stuff to check out
