    Grow Easy Alum Crystal

    To grow these crystals you will need:

    • 1/2 cup hot tap water
    • 2-1/2 tablespoons alum

    Simply stir the alum into the water and wait for crystals to grow. Alum crystals usually are visible within a half an hour and reach a good size within a few hours. It's that easy! When the crystals are to your liking, use a fingernail to scrape them off the side of your container. You can examine them and keep them.
