Copper Cube Cu 99.95% Element Cube Pure 10mm Density Cube for Element Collection Periodic Table Hunter, and More (0.39", Copper)

It's a very good cube of tungsten. Super heavy despite size. The edges are sharp so I had to be careful but it's good. A perfect tungsten cube.

I bought this Tungsten cube and an Aluminum one - the heaviest and lightest metals you can hold in your hand safely. The contrast is amazing.

Small, well made with nice sharp edges. I do love these little element samples for various purposes.

Solid chunk o mass that's fun to fiddle with when ye ain't paying for it to investigate online phenomena like 35% of the stuff I spent money on the last few years.

The product itself is great and high quality.The problem I have with it is probably my fault in that I expected the weight in the hand to be more noticeable between this and an aluminium cube if the same dimensions.I can still use them to get the density point across by utilising scales. However I find that most people are not that shocked by the density difference when just holding them in their hands.I have held larger examples of tungsten and aluminium in my hands and the difference in density is made much clearer by those larger cubes. I was hoping to get similar impact at a lower price.

Good

These are cool for the STEM kids. It helps complete the other set. A little pricey but of course will last a couple lifetimes. They are small but when you get them all it makes for a nice nerd display.

Ok so it’s a little pricy….but it’s so cool! The weight of this small cube truly is mind bending. I cannot express how cool it is to hold this in your hand. This is proudly displayed on my desk and is a great conversation piece!
