Worthy of its own post here. > Eventually, scientific analysis of the water revealed the magic behind the petrification process. The water has high mineral content that precipitates over objects creating a hard shell of mineral over it in much the same way as stalactites and stalagmites form in a cave. What’s amazing, however, is the speed at which petrification occurred. Rather than centuries, small toys like teddy bears can petrify in just three to five months. Teddy bears are popular because they are porous which allows water to soak in and petrify the toy inside out. Other have left personal items such as rings and clothing, kitchen utensils, and even a bicycle.
