Not sure if the galls are the same in Americas, but here in the Mediterranean, the galls are hard and wood-like balls.

I always entertained an idea of fashioning some of them into nests, but I have never opened one. Until today.
I assumed them to have a thick shell and be hollow inside...based on knocking sound they make when knocked against one another.
To my surprise, the shell is actually quite thin (but hard), and the insides are filled with a peculiar substance...a crossbreed between cork/sponge/dirt. It is solid, but crumbles to dust when scraped with an utensil.
