More properly called a garden of rock crystals, this charming little garden grew from a small kit my daughters included in my sock this past Christmas. All I had to do was place the rocks provided in a small glass bowl and cover them with distilled (white) vinegar. Voila! Two weeks later, the vinegar has evaporated, leaving behind these teensy little crystal “flowers”. A few drops of food colouring provided the “blooms” which were otherwise white. Another fun science experiment — isn’t Nature grand?
