You can create some really beautiful effects with this salt art craft. Kids also enjoy coloring the salt with food coloring before painting with it.
Pour half a cup of salt into a Ziploc bag and add several drops of food coloring.
Close the bag tightly, making sure that most of the air is out. (You can add more food coloring to get more vibrant colors of "sand.")
Use your fingers (on the outside of the bag) to mix the color into the salt. Pour the salt in a thin layer on the newspaper and let it dry.
Repeat this for each color, giving each its own piece of newspaper. (You can use half of a page.) When all colors are dry, pick up the papers one at a time and pour the salt back into Ziploc bags or into separate compartments in an egg carton.
Mix together glue and water in equal amounts. (If you use two tablespoons of water, use two tablespoons of glue.)
Put a piece of construction paper in the tray. Use a pencil to draw the design you want and then use the paintbrush to paint (glue) the areas where you want only the first color to stick.
Use your fingers to sprinkle the first color over the areas you painted. Wait a few minutes to allow the salt to stick and then hold the paper over the tray to let the "extra" salt fall off of the painting.
Pour the "extra" salt back into its container - you can use it again. Repeat step six and seven until you have all of the colors you want in your painting. Voila! You have created "sand" art.
