Rock salt is just coarse-grained table salt. Many stores sell it by the pound in bags. If you can't find any, then with a little work it's not hard to make your own.

Steps
- Heat some water.(But not too much water or will not work out!!!) While it's heating, dissolve as much salt in it as possible. Keep going until the water gets to the boiling stage.
- When the boiling water cannot take any more salt (a saturated solution) take the mixture off the stove and let it cool. The salt will form crystals as the water evaporates.
- Crush the salt crystals, and you've got rock salt.
- This is exactly like making rock candy, which is crystallized sugar. But don't give the salt crystals to anyone to eat.
- You may have colored rock salt by adding a couple drops of food coloring to the boiling mixture.
