Kitchen Cabbage Plant

The headline at reddit said, “Here's what happens when you leave half a cabbage in the fridge too long.” I clicked, thinking it would be a gross pile of mold, and was surprised to see this pretty plant. The photographer H0B0Byter99 said the cabbage was in the crisper for several months, and had sprouted about three inches of new growth. Then he set it in a bowl of water out in the kitchen, and watched it grow. I've done this with carrots and celery. Now, if anyone can figure out what’s in the bottles in the background, you’re smarter than I am.
