Make a Crystal Sun Catcher
Spring is finally here! Catch some of those wonderful rays of sunlight with some home-grown crystals. Add food coloring to change the colors of your suncatcher.
Clear Plastic lid from a container
Food Coloring (optional)
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!
