I wanted to show a picture of the interior and exterior of a thunder egg; most pictures on the Web show only the polished interior. The picture below is an example:

What is the difference between a "thunder egg" and a "geode"?

And we were just disgusting whether or not we'd ever want to see Natlie and the other Dixie Chicks lay "thunder eggs" on stage in their latest tour!

Very interesting. Reminds me of "pop rocks" (NOT the candy). Perhaps someone on this thread can tell me about them.

In the red clay and sand here in West Tennessee, there are often erosions we call "gullies". Growing up, my cousins and I had all kinds of fun playing in the gullies, and we'd often find what my grandfather called "pop rocks". He said if you put them in a fire, they would burst and make a loud popping noise, because they were hollow. We never tried that, but we almost always broke them open. In the cavity, there was usually some really pretty purple sand. Sometimes it was more red than purple.

Do these have a name? How are they formed?
