Plastic Test Tubes (2) with Screw-On Tops

 How does acid rain destroy statues?

 

Ingredients:

  • Test tubes (provided)
  • Chalk ½ in long (not provided)
  • Some vinegar (not provided)

 

What to Do:

  • Hold the test tube and put a piece of chalk inside.
  • Pour enough vinegar to cover the chalk
  • As you add the vinegar to the chalk, observe what happened.

 

What happened?

The vinegar is an acid, obviously much stronger than acid rain, but can quickly show the long-term effects of acid on limestone statues (most statues are limestone). Chalk is made of a variety of limestone substances.  The acid reacts with the limestone and dissolves the statue. Over many years acid rain can have a strong effect on statues.
