Aren't they beautiful? Here's how 'ghost apples' formed on this apple tree in West Michigan.
Ice forms on rotting apples, and as the apples decay, they slide down and out of the ice that is left behind hanging off the apple tree branches.
There's a longer explainer here:
Andrew Sietsema sent in photos of the hollow ice apples to ReportIt late Wednesday night. He said he came across the interesting formations while pruning apple trees earlier that day.
Sietsema said the freezing rain coated rotting apples, creating a solid icy shell around them. When he pruned the trees, they would shake, causing many of the frozen apples to fall off, ice and all. However with a few of them, the mush slipped out of the bottom of the ice casing, leading to a "ghost apple."
Sietsema the temperature provided the perfect recipe: it was cold enough for the ice to remain, but warm enough for the apples to turn to complete mush, since apples have a lower freezing point than water.
Sietsema said Jonagolds are one of his favorite apple varieties, "but we'll call these Jonaghosts."

Teams of researchers are developing sesame seed-size neuro-implants that detect brain activity that signals depression and then deliver targeted electrical zaps to elevate your mood. It’s very early days in the science and technology but recent studies suggest that we’re on the path. Links to scientific papers below. Fortunately, the goal is to develop tools […]
In the 1960s, when Scientific American copy editor Michael J. Battaglia was 15, he had a chemical romance with the periodic table. In fact, Battaglia was so fascinated by the basic substances of our universe that he tried to collect ’em all (at least the 104 elements that science knew about at the time.) From […]
