Friday Fun!

Your kids will be amazed when you tell them they can make their own crystals!

Materials
- charcoal briquettes
- vinegar
- salt
- warm water
- food color(optional)
- small enamel or glass bowl

Directions
Add three tablespoons of salt to half a bowl of warm water and stir until it dissolves. Keep adding salt until no more will dissolve. Add a tablespoon of vinegar. For colored crystals, add a dash of food coloring. Fill up the bowl with charcoal. Leave in a safe place without moving for a couple days. Take it out and notice that crystals have begun to form. As the water continues to evaporate, the bowl will be filled with rock crystals.
