You’re really adding value to the house, by the time you move someone with be able to set up an aluminium mine.

1:54 "after about 8 minutes cooking on the fire we got our first crack rock." Spoken like a true Florida man.

Here in Wales, the ground is wet almost all year round, especially in wooded areas. Once when I was out camping with friends, we had a rather large rock explode into 3 pieces, which actually sent some embers at us. we later found a hole in a camping chair that was nearer the fire, and we could only guess is was a rock shard.

You know, as a kid, my grandpa always told me “never use river rocks for a camp fire, you might just lose an eye.” I never really understood why, but it all makes sense now.

Absolutely. Ask my friend who used sand stone to put around the fire and his wife ended up going to the emergency room to get the grit removed from her eyes and several stitches on her arm.

Yes. Had a campfire rock go bang next to a fire. It was on the West Coast Trail in British Columbia, and our fire was right next to the ocean where we were camped, and with a very large boulder. It was kind of scary. Then we threw our magnesium bars into the fire, which lit up the whole cove we were camped in. It was a memorable night for a kid. The end.

I'm starting to think you should invest in a blast shield.

How about, for a laugh, making concrete with a good amount of Thermite mixed into it? The 'best' exploding rock, is Flint, by the way, with the added joy of when it explodes, it throws out glass-like shards of hot stone. If you really want an injury, heat stones to red hot - then chuck water, as cold as you can get it on them. Then call the hospital.

I’ve had more danger from bits of exploding log going everywhere than bits of rock, but I live in the Southwest so wet rocks aren’t super easy to come by; bits of dry brush that are waiting for a stray spark, however, are every five feet.

I live near a stony beach and have definitely witnessed rocks popping in fires. Slightly off topic whilst remaining somewhat on topic though the story that haunts me most was a friend telling me about a guy he knew that decided to cook an unopened tin of sardines on a bonfire which exploded red hot shrapnel into his eye. I had to mention this as it's all I could think about during this video

Imagine having to cut this dude's grass and hitting concrete and metal everywhere.

Honestly this can be pretty dangerous, we had a concrete ring around a fireplace once and it exploded without any warning, there was a 4-5kg piece that flew about 50m past my dad nearly hitting him. Im sure if that concrete slab did hit my dad, he would be no more. :(

have observed this phenomena up close and personal many times. porous sedimentary rocks and layered metamorphic rocks are quite prone to cracking and spalling sometimes quite violently. The fragments never reach a dangerous velocity but getting hit in the eye could be serious. Such rocks that have spent a lot of time submerged in water can be VERY violent with much larger cracking and spalling events. The real danger is the fire itself being ejected from the firepit onto the people near it and into flammable vegetation or materials nearby. On a couple of occasions I have had the entire contents of a firepit ejected by large spalls off of rocks buried in sand below a firepit.

At boyscout camp, we had a rock blow up. Sitting around the fire listening to scout master Jim tell stories a rock blew up. Scared me alot, so i slept in Jims tent. Long story short, im getting a settlement of $50k

Thebackyardscientist: can rocks explode Me, an intellectual: pOp rOckS

Yes! Exploding rocks are a thing and lemons/limes as well! Pretty crazy stuff. I was camping in Utah and we used dried river rocks to make a fire pit. About a half hour or so went by before two explosions went off. It was one of the scariest moments of my life because of how peaceful it was before and it was very unexpected.
