I was exploring up the north east with a freind and we found a play area in town. For a laugh i hit the sand pit with my fire axe. Next thing im hearing fire all around me and im bricking my pants. My mate is screaming wtf is that so i tell her to hit the other sand pit. Woosh a fireball erupts all around her and the sound of fire again! Completely surprised by this, I knew axes make sparks but who put petrol in the sand lol. Anybody else found this?
