The steps to making Salt Crystals
Mix 2 tablespoons of salt with 4 tablespoons of water, stir to dissolve as much salt as possible. Now add 2 tablespoons of ammonia and laundry bluing keep mixing till gooey. The mixture will be a blue, water sludge. Pour sludge liquid and extra salt, on top of the porous substance in plastic container.Make sure to get all of the salt out of the mixing cup and on to the porous in the plastic dish ( Note: if you use a sponge, get it wet first and squeeze dry for better sludge). All the salt may not go into the solution; this is okay as long as you pour the extra salt on top of the items in the dish. The porous materials in the dish will not immediately soak up all the liquids; this is okay. The crystals will natural grow white, like the salt. If you want color crystals, add a drop or two of food coloring on each item in the dish. The crystals will grow that color.
Allow the container to sit open to the atmosphere overnight .By the next day,crystals should have formed on the item in the dish and your crystal garden should be starting to bloom.
