What is limestone?
Limestone is a sedimentary rock made of bones, dirt shells, mud, sand and pebbles. It contains at least 50% calcium. It was made in the sea, the desert, lakes and rivers billions of years ago.If you put limestone in vinegar  it starts to bubble like the bottom of a big bottle of lemonade when you open it up. After a couple of days soaking in vinegar it forms tiny white crystals.
