Instructions 

  • 1. Measure You will be using a ratio of 1:1 water to Epsom Salt for this project. Add 1 cup of Epsom salt to a bowl or large Pyrex measuring cup.

  • 2. Heat 1 cup of water it does not need to get to boiling temperature. (You can use the microwave or a kettle)

  • 3. Carefully pour the water into the bowl with the salt. Do this quickly so that the water is warm. Add food coloring if desired Stir the salt and water for 1-2 minutes to dissolve the salt.

  • 4. Place several plastic lids on a flat-bottomed tray in a sunny location where they can remain undisturbed.

  • 5. Pour some of the liquid into the recycled plastic lids. Use just enough to cover the bottom of the lid. DON’T OVERFILL!

  • 6. Leave your lids in sunny location. Depending on how much liquid has been added it will take a few hours or a day to start crystallizing. I know it will look like lids full of water at first but be patient!

  • 7.  When the liquid has completely evaporated your crystal suncatcher is ready! You will be able to see lovely crystal structures from both side of the lid.

  • 8.  VERY carefully poke a small hole in the edge of the lid and thread a piece of string through the hole. Tie in a knot and hang your suncatcher up!
