Materials Needed:

  • Vinegar

  • Shells, rocks (hopefully limestone)

  • Glass cup or jar

Get Started:

  • Pour the vinegar into the glass container
  • Add the shells and rocks.
  • Notice which ones give off bubbles.
  • Do all parts of the shells and rocks give off bubbles?

What does this mean?

  • Limestone and shells are carbonates.
  • When they come in contact with vinegar there is a chemical reaction, which produces carbon dioxide gas (this is the bubbles).
