He won't do that again. I saw a fire consume a newly framed up house and the bed of coals above the relatively new concrete caused explosions that looked like land mines going off every few seconds. The debris and coals went yards into the air and were quite loud.
My son damn near had an eye knocked when a stone from our lake was placed around the fire pit and exploded. Only a small cut thank god. Quarter inch higher and it would've struck his eye. The shards from that rock were almost like glass
Southside Tony is absolutely correct. Never use a a stone from any body of water (sea, lake, river, etc.) because it will explode like a landmine. Always use rocks from a high and dry place ... if you cannot afford a frying pan.
Forest fires in Idaho have caused boulders to explode, but not until they cool down rapidly at nightfall. I've seen it, sounds and looks similar to lightning striking.
