Ice-star

Print the mold. Put a cord or thread loop with a knot inside. Fill the mold with hot! water to make the star cristal clear in the end. Let it freeze outside overnight. Bing it into the house and wait a moment to melt the outer layer. You can help a litle bit with your warm hand or fingers esp. on the edges. Move the ice star out of the mold and put it into the tree.
