Crystals Recipe

  • bluing
  • ammonia
  • salt
  • liquid food coloring

Day #1: Place damp sponge pieces in a shallow glass or plastic bowl. Pour 2 Tbsp. each of bluing, salt, water and ammonia over the sponge pieces.

Day #2: Add 2 Tbsp. salt.

Day #3: Add 2 Tbsp. each bluing, salt, water and ammonia. Avoid pouring on the crystal growth because the crystals can be easily damaged. Repeat Day #3 as needed to keep the crystals growing. For color, add drops of your choice of food coloring.

*Bluing can be purchased in the laundry section at the store.

    Will this continue to grow as long as you add “day 3″?

    Bluing is a liquid purchased in the detergent isle?

    Thanks,
    Michelle

      Michelle yes and yes. :) Bluing is usually in the laundry detergent section although it is often on a high or low shelf in that area.

    I needed this at Easter! I had purchased a $1 kit for making crystals from Target for my son’s Easter basket and it didn’t have instructions with it–we got it to work, but this would have been so much simpler. :)

      just an FYI…this is a toxic project and all warning lables should be adhered to, especially if you have young children or curious pets.

    Interesting… haven’t seen this before. Looks like a rock in the photo rather than a sponge piece. Must you start with sponge pieces? If so, any requirements for the type of sponge? (ie. must it be natural sponge?)

        In your picture the crystals are more dense and clear how did you make such pretty crystals I got the white cotton candy looking fungus

    My mom and I used to make these in a bowl and used charcoal pieces as a base. Looked like a rock garden!!
