This homemade colored salt is fun for so many different activities!
3 tablespoons salt (Coarse salt or rock salt would look better.)
About 2 drops of food coloring (Depending if you need to mix colors to obtain a particular color.)
Place the salt in a sandwich bag or sealable bag. Add the more than one food coloring to make various colors. Seal the bag. Move the salt around using your fingers. Keep the bag open. Let dry. (It usually takes a half a day or less.)
If using table salt, place in salt shakers by cutting a hole in the bottom side of a sealable bag. Place it in the salt shaker.
If you use coarse salt, have the child spoon it onto the glue or use his/her fingers.
Place glue on paper, sand paper, etc. Sprinkle the salt onto the glue. Shake off the excess salt. Let dry.
