These images are crystals that I grew from a kit for children.
The red crystals are 24 hrs old and still in the red solution.
The blue crystals are 7 days old. They creeped up the side of the container and grew on the edge. The tiny blue specks are from the "coloring seeds" used to give the crystals color.
I am always amazed at the detail and beauty of the Lords handiwork.
