  • You should also make absolutely sure there are no old tree roots beneath the pit because fire will travel along the roots underground.

  • wtf, are they dumb or somthing. river rocks usually contain trapped water inside, if heated to a degree the water will expand thus exploding the rock. in other words a shrapnel grenade.

  • Do you guys not pay attention at all? At 1:25 he SAYS "behind the stones, we place FIRE BRICK".

    Also, @ MrShawnsquatch re: painting the inside: WHO SAID ANYTHING ABOUT "SEALING"??? He didn't say seal, he said PAINT.

    The only sensible thing you said was about putting the stones in the bottom. That IS a bad idea.

  • Regardless of what "Stone" is used - its stupid to put loose stone in the bottom of a firepit. Beside the exploding stone issue - please explain to me how you remove ash? You'll have to pull every tiny stone out! That's just poor design and stupid...

  • Notice, "FIRE BRICK" is used to prevent the exploding rock.

  • river rocks heat up and blow up that mad dumb those people will be really supised hahaha

  • I don't even understand why you need to put stone in the bottom. If you build any real fires all that rock will soon be covered with ash. Just dig up the sod and build the fire on the dirt. And sealing the inside of the stone with paint is a bad idea. It chokes off the air coming through the cracks and the fire wont burn as well. It seems to me that most of these DIY fire-pit jobs waste alot of money to built a pit that could barely hold a couple small sticks and a couple flames.

  • great recommendation on the river rock! or not...... it explodes when it get hot....... way to go on the how to

  • Terrible recommendations here.I would not use their advice on fire pit construction

  • that was nice and funny

  • i guess it was a good video it went so fast and the "cool" swirling images were uh shall i say confusing -major do-over

  • i just watched a video that said do not use river rock it can explode!!

  • Pack the bottom with an inch or so of sand and top it off with broken fire brick. Like the previous people said...only an idiot would use river rock with fire. You may also want to consider burying a five gallon perforated bucket (akin to a septic tank) connected to the bottom of the fire pit via a one inch steel pipe if your fire pit utlimately will have a concrete base to keep rain water from pooling.

  • Those stones they placed at the bottom WILL explode when they reach a high temperature. I built a firepit with fieldstone and other large stones, sitting around it one night drinking beer with a couple friends one of the huge stones exploded with a big bang, a piece hit this guy in the forehead giving him a nasty cut, also when it explodes some of the stone turns into a fluffy fiberglass like insulation, yeah sounds nuts but try it yourself, so now I use firebrick. Beware of exploding stones!

  • yes, any porous stone, may explode, any geode, can explode.

    any damp stone, specialy the porous ones, are likely to explode.

    the water in the stone, yes stones can have water in them, expands, thus breaking the rock

  • @TheGreenhorseman They only explode if they were near a water source

  • River rock has small amounts of water within it. If it does get to hot it will "explode" throwing debris.

  • I thought river rock was combustible??

  • i thought so to
