"Perhaps I was a bit to negative. But still, did they mention any "grade" on the exploding stones? I belive that they might crack and even send small bits flying. I'm just wondering if it's going to be some fatal barrage of lethal rock shards simular to a stone wall exploding and sending shards that penetrate the human body?

Can't you just stuff the "bottom" of the firepit (above the stones) with a whole bunch of grass, or even bury them (not that deep) to minimize the impact of eventual flying stones?

I think it's rather hard to find a bone dry area of the ground in many areas.

I though the idea was to point out flaws and try to find solutions?

"Can you rate this "explosive" quality? For example, just how loud a noise do you get, or how big are the fragments and how far do they travel?

So far I have done this once since posting, and had no issues. But maybe it needs some specific conditions that I haven't reproduced yet."

"Dear Lord, I saw the author of this thread and thought MD was back."

"To those confused, this is the point of this decades-old warning: It's a hazard, not a deathtrap.

Not all wet rocks explode, but some do. Not all exploding rocks can puncture skin, but some can. It's not going to blow your leg off, but it might cut it.

In a survival situation, a small cut can turn into a serious infection, which is the main point of this caution, really.

It's like walking around on the top of a very tall building in a thunderstorm, holding a 12-foot piece of piping and hoping the lightning won't flash. If you can avoid it, do. If not, just be careful. Odds are that nothing will happen, but it's still a hazard.

By the who, didn't some rocks blow up on Les Stroud at one point, or am I remembering wrong?"
