With little or no expense and very little effort, it is easy to make colorful crystal projects. For rock collectors, the finished crystals can be a pretty addition to their collection.

Video of the Day

Place the salt into the sandwich bag.

Add two drops of food coloring. If you are planning to use two colors, for example, red and blue in order to make purple crystals — use only one drop of each color.

Seal the sandwich bag and then shake and manipulate the salt inside so that the food coloring coats the salt crystals.

Unseal the sandwich bag to allow air in the bag.

Allow the crystals approximately eight hours to dry and be useable for other crafts.
