Rocks That Explode Around Fire Pits | Hunker

Air- and water-permeable rocks are much more likely to explode than dense non-permeable rocks. This is because air or water is absorbed by the rock when it is cool, and then the air or water molecules trapped inside the rock expand faster than the solid rock when it heats up next to the fire . If there is a high enough volume of water in a hot ...
