SULFUR ELEMENT CUBE

Sulfur is element 16—a brittle, yellow crystal that's been around since ancient times. This nonmetal is essential for life, showing up in amino acids and keratin, and it's got quite the personality: burn it and watch it melt into a blood-red liquid while flames turn blue! Found near volcanoes and hot springs, sulfur powers everything from fireworks and matches to rubber production and fungicides. A fascinating piece of elemental chemistry in cube form.
