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.
Yup. If the water turns to steam (mainly in sedimentary rocks) they can explode quite violently. A simple temperature differential won't cause an explosion, that merely cracks it. So you need porosity.
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.
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.
Actually another fun thing to try might be to put a bunch of rebar in the middle and then wrap a loop of electrical wiring (or just more rebar) with two ends sticking out. Apply a high frequency high current to it to heat up the rebar from the inside. Wonder if the expansion would make it explode.
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.
My first thought is it's not a rock per se it was probably a geode they have liquid inside sometimes if not fully formed those would most likely explode.
@@wireknight First-degree burns are considered mild compared to other burns. They result in pain and reddening of the epidermis (outer layer of the skin). Second-degree burns (partial thickness burns) affect the epidermis and the dermis (lower layer of skin). They cause pain, redness, swelling, and blistering. Third-degree burns (full thickness burns) go through the dermis and affect deeper tissues. They result in white or blackened, charred skin that may be numb.
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
Don't say 'crack', Jez, please. Not now. Because when you say 'crack', it makes me think of crack, and... I really love crack. So can you not say 'crack' ?
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.
when camping, me, my brother, and my cousin would take river rocks and put them in the direct center of the campfire with all the coals, and then take them out with tongs and dunk them in a red solo cup full of water. it's a miracle we aren't dead
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.
Could you imagine living with this guy, you’d be asleep at 7 o’clock in the morning and then all the sudden you hear a bang and then other bang and then there is aluminum shrapnel flying at your window
"how did you die?" "well, i took a shot for my beloved wife and saved her life" "i died in a plane crash, i didn't even get to finish my last wishes" "and what about you?" "i got hit by a concrete grenade"
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.
One time I was sitting at a fire that was sitting on concrete about an hour later the ground under it exploded and before seeing this video I did not know why but now there is a big crater in my friends drive way
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
NEVER pour a concrete floor in a fire pit! I mistakenly did, and even though I put in a drain pipe for draining off rainwater, I hadn't considered all the sand underneath the concrete that was still able to absorb ground-water that was naturally there. Weeks later I started my first campfire in it, and it was quite large being as it was a 4 foot wide fire-pit. About 30 minutes later there was a horrendous KABOOM and flaming firewood and chunks of concrete shot up out of the pit at least 30 feet in the air! Luckily no one was sitting around the fire pit at that moment, but it scared the sh*t out of all of us there.
Any cement that you build a fire on will explode. Its well documented and would have been easy to look up. They make specific mixes for contact with fire. Its stored right next to the cement you bought.
A similar story happend to me, I once put a piece of concrete drain pipe in a fire, and a few hours later it exploded and a piece of croncrete hit one of my friend right below the eye, quite scary.
And that's why you use dry rocks to make your campfire perimeter. How do you know if a rock is dry on the inside? You don't really but it's a good bet that rocks that have been under the sun all day are probably dry inside.
We had “smart” friend put river rocks below our campfire to create a platform (even though we told him not to). Let me emphasize that these were RIVER rocks, as in taken directly out of a river that they were probably in for thousands of years. The rest of the night was spent avoiding shrapnel that was flying 20-30 feet away.
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. :(
I found out this same thing happens with wood. When dumping water on a wood fire to put it out, do it slowly… I poured a 5 gallon bucket water on a standard camp fire and the whole thing blew up into splinters covering me head to toe in scalding water
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.
Usually that is also how the pine cones distribute seeds. the seeds are inside the pine cone, then once it pops open then the seeds can plant new trees.
I was tending a fire with my friends and we had used flat river rocks to stop the grass burning The rocks burst almost in half and shot embers in a 3 meter radius I have a scar on my shin from kneeling on one we didn’t find
When I was younger with a few mates we had a bonfire on a concrete pad and the concrete started popping and throwing little bits of concrete everywhere even chipping a car window
I'd be interested in reading the description when you sell your house, and what you'll put down in the disclosure 😀 Great house 4 bed 3 bath, tons of space, may or may not find various metals and glasses from explosions. Swimming pool had lava dropped into it, and the other normal backyard scientist stuff.
It was like 1 am and something hit me and burned a clean hole through my trouser leg, I told my friends but they denied it until the fire properly started exploding. There was like a pop every 10 seconds and it was throwing hot shards of rock at us. Thank you for this video, it’s a life saver 😭
I have had rocks explode on me before, the most dangerous was a flint rock that had been in a river. It became shrapnel and and at least three of the tiny shards hit me in the face and gave me tiny cauterized cuts where they hit. Took forever for them to heal and I had scars that took several years to fade. I did a bit more research and found out that both flint and slate are notorious for exploding into shards. It is mostly because of the way they layer and makes it easy for moisture to be trapped inside and expand in all the layers. It is far more dangerous with them if they are saturated though as I learned the hard way...
@Kody Choates you get hit in the face by the equivalent of scalding hot peices of glass half the size of your fingernail and moving at a very high velocity. If one had hit me in the eye rather than on the cheek and forehead I very well could have been blinded by it. I actually didn't cry when it happened and really didn't realize just how bad it was because they didn't bleed and I had no mirror. But I had rather obvious red welts that surrounded the actual burnt and cut skin for several weeks and the cuts themselves itched forever while they healed. They didn't even really hurt until several days later. I had also got hit in the arm too by a larger peice that did bleed and hurt quite a bit but I just put a bandaid on it and that was it. Didn't even know I had the others till I got home and looked in the bathroom mirror.
one time i was cooking chicken on a flat rock (possibly slate) in a camp fire and me and my friend were starting at it as we were a foot a way and the whole thing blew up in out face and the ash went everywhere
Any type of rock can "explode" like this, and there are three causes related to external heating/cooling: 1. Expansion/boiling of water in cracks/fractures or porous surfaces. 2. Localized thermal expansion/contraction, like putting a drop of water on a hot incandescent light bulb. 3. If lava contacts water, the water can not only flash to steam, but also be separated into hydrogen and oxygen... you know the rest, lol.
My experience was when I was around 6 and we were playing near a dump site where trash was burned. We decided to throw rocks into the fire and they exploded. They produced loud bangs. We did it repeatedly to make sure that it was really the rocks/stones that were exploding. We threw relatively smooth stones that were laying around to be used as ground fillers.
We used a flat stones to cook on once. When it exploded it was like a war zone. It shot our cooking pan like 30ft into the air. The rock pieces that were falling from the sky were exploding mid air and when they were hitting the ground. My friend almost had a rock piece hit his eye. Luckily we were all unharmed, but it was the most surreal things that ever happened to me.
I remember when I was younger me and my family were in the Catskills sitting around a campfire, as I walked by rocks started to explode and I jumped and fell into a little kiddy pool
If you get a Baryte crystal, you can simply put it under warm water from the spring, and it will explode. Because of the tight molecule structure, for the same reason it is pretty heavy too. This has made many mineral collectors sad, as they come home with this and try to wash them in warm water.. lol
I use the rocks as a molotov. Pour oil on the rocks and heat it up. Then attach a lighter that's still turned on then throw it. Done, you just crafted a molotov
I know this is an old video of yours. But I think you should revisit it with rocks called Moqui Marbles. I know they are found here in Utah and I’ve personally been injured by them exploding in the campfire. I believe they explode so violently because they have are a soft sandstone surrounded by a hardened sandstone, allowing a ton of pressure to build.
I have been told as a young child that when you're in the sauna, the kiuas (the heater with rocks on it) should be only watered with decently warm water, or else the stones will crack (not explode tho).
i think thats too avoid putting cold water on hot rocks, because that will crack them for similar but still different reasons to what happened in this video
I'm 30 years old and grew up camping my whole life. I have thrown so many rocks into the fire pit over my lifetime and only ONCE experinced a rock explosion. I was in Idaho on a camping trip with some buddies and we were just hanging around the fire late at night talking when out of NOWHERE a random stone that was already in the firepit when we got there exploded and set off a mini stone confetti that hit a handful of us on the head and face but thankfully not in the eyes. It was insane at the time... it's cool to see him share the science behind it.
Physicist: "in theory concrete could explode" Chemists: "I reverse engineered the concrete so I could make the most explosive possible mixture. Let's try it out!"
It's more impressive if ya use a different molten metal... Here's two 'suggestions' for you to try on really wet concrete 1: Potassium 2: Tungsten For 'added 'effect' instead of just water wet concrete, use some WFNA wet concrete
When I was on a camping trip with my JROTC group and we used river rocks as a makeshift stove top with a fire underneath. I thought the can had exploded but it was the rock. It shot hot beans all over my friends and they had to be treated for burns and our trip was called short. They literally thought we had fireworks and we would’ve been kicked out but all of our stories matched and one of them went off when someone dumped water on the fire.
I once arranged some rocks in a circular formation and placed a grill on top in order to cook. The stones didn’t look wet but we were at a swimming quarry so it’s possible they had moisture inside. While I was stoking the fire one of them exploded with enough force that if I had been hit I bet some of the sharp pieces could have drawn blood. Definitely made me jump. I imagine the stone I used was sand stone.
the other day we had a sewer campfire with an old pallet that must've gotten soaked because a bunch of wood started exploding sparks everywhere it was actually kinda dangerous but probably infinitely better than exploding rocks
@@akramisalah8189 posted up in this concrete tunnel by local creek . the kind u can walk upright in. it opens at both ends but once my bro stupidly lit an old xmas tree on fire in there and it created like an instant fire jet backdraft situation lol
One time when I was younger me and my father finally convinced my mother to come sit by the fire and a rock exploded and hit her in the forehead from like 10 ft away
I was camping with a few friends and I brought some rocks I grabbed from a nearby creek to make a ring. After we made our makeshift camp fire, we lit it on fire. We kept the fire going for an hour or so. As we were talking about how calm the woods were, the rocks began exploding. Out of pure instinct we jumped off our sitting spots layer flat on the ground and covered our heads. When we realized it was the rocks that had exploded we put out the campfire with our water… and some pee. My friend got hit on his arm and we took a rag and wrapped it around the wound cause. It wasn’t that bad but being teenagers that got scared shitless, he did what we thought was needed. It bled only a little but everyone was fine
Had a rock "explode" when we went to put the fire out. It was a good size rock. We poured water on the fire and the rock shattered into about 10 pieces and sent pieces all around the fire pit
Me and a couple of buddies ended up learning this the hard way when we were on a scout camping trip. We had a camp fire going in a little shelter area while it was pouring out and we had the genius idea to put rocks into it, because you know, why wouldn’t that end badly? Well, flash forward a few minutes later, and we start hearing this popping sound coming from the fire. All of a sudden, one of the rocks explodes, going off like a gunshot, sending a really hot piece of rock right into my friends hand. Long story short, he got a second degree burn on his hand and had to go to the hospital. On the bright side, we now have a funny story to tell people and he got to skip out on the pouring rain the rest of the camp out!
Yes, I've seen rocks explode in a campfire when we made the fire on the rock bank next to the river. It's not super dangerous, but the hot rock chips that break off can easily melt through nylon or polyester sleeping bags and tents.

Great house 4 bed 3 bath, tons of space, may or may not find various metals and glasses from explosions. Swimming pool had lava dropped into it, and the other normal backyard scientist stuff.

It was like 1 am and something hit me and burned a clean hole through my trouser leg, I told my friends but they denied it until the fire properly started exploding. There was like a pop every 10 seconds and it was throwing hot shards of rock at us. Thank you for this video, it’s a life saver 😭

I have had rocks explode on me before, the most dangerous was a flint rock that had been in a river. It became shrapnel and and at least three of the tiny shards hit me in the face and gave me tiny cauterized cuts where they hit. Took forever for them to heal and I had scars that took several years to fade. I did a bit more research and found out that both flint and slate are notorious for exploding into shards. It is mostly because of the way they layer and makes it easy for moisture to be trapped inside and expand in all the layers. It is far more dangerous with them if they are saturated though as I learned the hard way...
@Kody Choates you get hit in the face by the equivalent of scalding hot peices of glass half the size of your fingernail and moving at a very high velocity. If one had hit me in the eye rather than on the cheek and forehead I very well could have been blinded by it. I actually didn't cry when it happened and really didn't realize just how bad it was because they didn't bleed and I had no mirror. But I had rather obvious red welts that surrounded the actual burnt and cut skin for several weeks and the cuts themselves itched forever while they healed. They didn't even really hurt until several days later. I had also got hit in the arm too by a larger peice that did bleed and hurt quite a bit but I just put a bandaid on it and that was it. Didn't even know I had the others till I got home and looked in the bathroom mirror.
Anf this is where he earned the name, Captain Flint.
one time i was cooking chicken on a flat rock (possibly slate) in a camp fire and me and my friend were starting at it as we were a foot a way and the whole thing blew up in out face and the ash went everywhere
Any type of rock can "explode" like this, and there are three causes related to external heating/cooling:
1. Expansion/boiling of water in cracks/fractures or porous surfaces.
2. Localized thermal expansion/contraction, like putting a drop of water on a hot incandescent light bulb.
3. If lava contacts water, the water can not only flash to steam, but also be separated into hydrogen and oxygen... you know the rest, lol.
Same happened to me
My experience was when I was around 6 and we were playing near a dump site where trash was burned. We decided to throw rocks into the fire and they exploded. They produced loud bangs. We did it repeatedly to make sure that it was really the rocks/stones that were exploding. We threw relatively smooth stones that were laying around to be used as ground fillers.
We used a flat stones to cook on once. When it exploded it was like a war zone. It shot our cooking pan like 30ft into the air. The rock pieces that were falling from the sky were exploding mid air and when they were hitting the ground. My friend almost had a rock piece hit his eye. Luckily we were all unharmed, but it was the most surreal things that ever happened to me.
I never had this problem in life, it feels like you introduced me to new physical problems I need to worry about.
I remember when I was younger me and my family were in the Catskills sitting around a campfire, as I walked by rocks started to explode and I jumped and fell into a little kiddy pool
Now that "Florida" tag is testament of crazy content
Facts my dude
There we are.
If you get a Baryte crystal, you can simply put it under warm water from the spring, and it will explode.
Because of the tight molecule structure, for the same reason it is pretty heavy too.
This has made many mineral collectors sad, as they come home with this and try to wash them in warm water.. lol
An electrical wire fell in front of my house, causing a small fire. The fire was so hot that the curb exploded, sending concrete up to 60ft away.
Vegas Rockafeller wth Final Destination much?
note to self: throw overheated rocks at the enemy and have a chance for then to explode in their face
This is what is called a *CHANCE GRENADE* has a 40% chance of dealing 100 damage, and a 60% chance of dealing 0. Also deals splash damage.
I use the rocks as a molotov. Pour oil on the rocks and heat it up. Then attach a lighter that's still turned on then throw it. Done, you just crafted a molotov
When I was younger I would throw rocks in a camp fire and when the crack I sometimes keep them cuz the inside looked cool
I know this is an old video of yours. But I think you should revisit it with rocks called Moqui Marbles. I know they are found here in Utah and I’ve personally been injured by them exploding in the campfire.
I believe they explode so violently because they have are a soft sandstone surrounded by a hardened sandstone, allowing a ton of pressure to build.

Timestamp?
Woah you watched the video too??
I have been told as a young child that when you're in the sauna, the kiuas (the heater with rocks on it) should be only watered with decently warm water, or else the stones will crack (not explode tho).
i think thats too avoid putting cold water on hot rocks, because that will crack them for similar but still different reasons to what happened in this video
Those rocks are very porous almost like a sponge. They can split from hot water but not explode.

I'm 30 years old and grew up camping my whole life. I have thrown so many rocks into the fire pit over my lifetime and only ONCE experinced a rock explosion. I was in Idaho on a camping trip with some buddies and we were just hanging around the fire late at night talking when out of NOWHERE a random stone that was already in the firepit when we got there exploded and set off a mini stone confetti that hit a handful of us on the head and face but thankfully not in the eyes. It was insane at the time... it's cool to see him share the science behind it.

When I was on a camping trip with my JROTC group and we used river rocks as a makeshift stove top with a fire underneath. I thought the can had exploded but it was the rock. It shot hot beans all over my friends and they had to be treated for burns and our trip was called short. They literally thought we had fireworks and we would’ve been kicked out but all of our stories matched and one of them went off when someone dumped water on the fire.

I once arranged some rocks in a circular formation and placed a grill on top in order to cook. The stones didn’t look wet but we were at a swimming quarry so it’s possible they had moisture inside. While I was stoking the fire one of them exploded with enough force that if I had been hit I bet some of the sharp pieces could have drawn blood. Definitely made me jump. I imagine the stone I used was sand stone.
the other day we had a sewer campfire with an old pallet that must've gotten soaked because a bunch of wood started exploding sparks everywhere it was actually kinda dangerous but probably infinitely better than exploding rocks

I was camping with a few friends and I brought some rocks I grabbed from a nearby creek to make a ring. After we made our makeshift camp fire, we lit it on fire. We kept the fire going for an hour or so. As we were talking about how calm the woods were, the rocks began exploding. Out of pure instinct we jumped off our sitting spots layer flat on the ground and covered our heads. When we realized it was the rocks that had exploded we put out the campfire with our water… and some pee. My friend got hit on his arm and we took a rag and wrapped it around the wound cause. It wasn’t that bad but being teenagers that got scared shitless, he did what we thought was needed. It bled only a little but everyone was fine

Me and a couple of buddies ended up learning this the hard way when we were on a scout camping trip. We had a camp fire going in a little shelter area while it was pouring out and we had the genius idea to put rocks into it, because you know, why wouldn’t that end badly? Well, flash forward a few minutes later, and we start hearing this popping sound coming from the fire. All of a sudden, one of the rocks explodes, going off like a gunshot, sending a really hot piece of rock right into my friends hand. Long story short, he got a second degree burn on his hand and had to go to the hospital. On the bright side, we now have a funny story to tell people and he got to skip out on the pouring rain the rest of the camp out!

Yes, I've seen rocks explode in a campfire when we made the fire on the rock bank next to the river. It's not super dangerous, but the hot rock chips that break off can easily melt through nylon or polyester sleeping bags and tents.
