How to Make Salt-Crystal Ornaments You will need two tablespoons of salt two wide-mouthed jars food coloring string pencil Directions 1. Make a snowflake shape out of pipe cleaner(s) (The snowflake should be small enough to fit in a jar without touching the bottom or sides.) 2. Attach one end of the string to the snowflake and the other end around the pencil. 3. In a jar, add salt to two cups of hot water. 4. Stir until all the salt fully dissolves (The mineral in the water should be clear.) 5. Position the pencil horizontally, over the jar's mouth. The snowflake should be in the saltwater (The string may need to be moved on the pencil for the snowflake to hang correctly.) 6. Before long, crystals will start to grow. Leave the snowflake in saltwater until the physical change results in a good snowflake. You can even leave it in the iar until the water evaporates 1 When finished, the crystals will most likely look like A. dust B. glass C. coral D. Silver. Reset

## Step 1<br />The problem involves creating salt-crystal ornaments using a snowflake shape made from pipe cleaners. The snowflake is then hung in a jar filled with a saltwater solution.<br /><br />## Step 2<br />The snowflake is left in the jar until the water evaporates, which causes the salt to crystallize around the snowflake. This process is known as crystallization.<br /><br />## Step 3<br />The question asks us to identify the most likely appearance of the crystals that will form on the snowflake. The options provided are dust, glass, coral, and silver.<br /><br />## Step 4<br />Considering the process of crystallization, the crystals that form will be solid and shiny, similar to glass. The other options, dust, coral, and silver, do not accurately describe the appearance of the crystals.
