Calcium


When you drink milk, did you know that you're also drinking some metal?
Calcium is a healthy ingredient found in milk, that helps us have strong bones and teeth.
You can't tell that it's metal because there's only a tiny bit of calcium in there, so little you can't even see it.

Calcium all by itself is a shiny gray colored metal.
