Photos Of Frozen 'Ghost Apples' Are Going Viral. What Are They?

These amazing frozen 'ghost apples' have been found by a farmer after a particularly cold snap in Michigan, USA. While they might look like the fruity version of Cinderella's glass slipper, they're actually made out of ice! But where do they come from? Can you eat ghost apples?

When their temperature drops to around -18°C (around 0°F), their structure collapses, and a few could "spew their rotten contents successfully." Although some may wonder why the apples didn't freeze solid during the polar vortex, Shoemaker noted that the apple has a significant acid content, so it would have to get exceedingly cold before it froze solid. "It's certainly unique, but I would guess it has happened before," he said, adding: "but it probably never had exposure to a journalist before."
