I bought a cube of tungsten and a cube of magnesium to teach my kids about density, and I was really surprised how dangerous it feels just to hold the tungsten. I only let them hold it a few inches above a table because that thing would break your foot if you dropped it! If you hold the magnesium and drop it one inch you get a delicate little “clop” and if you drop the tungsten one inch you get a solid “BANG”.
