Add 1 cup of Epsom salt to your jar\/votive. \u00a0If you are working with larger jars feel free to add more salt but be sure to make a note of how much so you can add the same amount of water.<\/li>\n<li><strong>Step Two<\/strong>\u00a0|\u00a0<strong>Heat the Water<\/strong>\u00a0Add 1 cup of water to a microwave safe bowl. Heat the water in the microwave for 45 seconds. Alternatively use very hot tap water and skip the microwave.<\/li>\n<li><strong>Step Three<\/strong>\u00a0|\u00a0<strong>Add Color\u00a0<\/strong>If you are using color, add a dash of food coloring to the water. Stir.<\/li>\n<li><strong>Step Four<\/strong>\u00a0|\u00a0<strong>Combine\u00a0<\/strong>\u00a0Pour the water into the jar with the salt. \u00a0Stir the salt and water for 1-2 minutes to dissolve the salt. \u00a0Don\u2019t worry if some of the salt remains undissolved at the bottom of the jar.<\/li>\n<li><strong>Step Five<\/strong>\u00a0|\u00a0<strong>Cool<\/strong>\u00a0Drop in a pebble or a few grains of sand. Crystals need something to grow on and one little impurity in the water like grain of sand will should help ensure they have a place to nucleate.<\/li>\n<li><strong>Step Six<\/strong>\u00a0|\u00a0<strong>Cool\u00a0<\/strong>Place the jar in the back of your refrigerator. Alternatively, quick cool the mixture for 10 minutes in the freezer and then move it to the refrigerator. Cooling in the freezer first yielded crystal growth in 90% of our experiments.
