While writing about dripping pine cones I learned that mature cones open and close many times and can do so for many years.
They do this in response to wetness — even after they release their seeds, even after they’ve fallen from the tree. In fact the open/closed status of fallen cones is a simple indication of wildfire risk because it shows the dryness of the forest floor.
So what does a wet cone look like? Can you tell which one is wet and which is dry, above?
Here’s a view of the tail end.
And here’s an overhead view.
By now you’ve probably guessed the answer so you’re ready to play Cone In A Bottle.
Put the closed cone in a bottle and wait for it to open. If you want to get the cone out, do you add water or remove it?
The answer is in the comments below.
