Later as we loaded up the car to leave, I moved a bag on the back seat. "What's in here? That BROKEN glass bottle??!!"
"It's just strategically opened," Caleb replied calmly.
So he brought it home, and it found a place amongst his other piles of junk. I have been giving it a dribble of water from time to time, thinking I might transfer it to another jar. The fronds are looking rather crisp, though, so I don't know if it has survived the low humidity of our house. I will have to wait to see if it shows more signs of life.
It's amazing how life can thrive in unusual places if given the right conditions.
