Review on 🔩 Density Metal Piece by Ajax Scientific by Chris Horton

I was trying to demonstrate an experiment before doing it with my class. It turns out 20 mm, but the density is wrong. I weighed them on an accurate scale, but only copper and aluminum seem to match actual density. Not to mention that it doesn't contain any information about which element is which cube. Good luck finding out. I ended up labeling one of these as tin because one of the calculated densities was closer to that of tin than any other mentioned in the product description.
