Funny story. I was in Boy Scouts once upon a time, and on one occasion my troop went camping in a cave. We set up camp in a large cavern with a ceiling that might have been 50 feet up. When we got settled in, we started a fire right on the cave floor to cook dinner. As we were standing around the fire, we started hearing a "tap, tap, tap" sound above us, apparently on the cave ceiling. Our scout master came sprinting over and threw water on the fire, putting it out. Turns out the cave floor was made of shale, and shale often has air pockets in it. Apparently, when shale gets heated it cracks. The air inside is pressurized, and the cracks give it an out. When the air decides to leave, it likes to send shards of shale flying. The sound we were hearing was the shale shrapnel from tiny explosions caused by our fire. Close one.
