Yup. Being young and stupid, a group of us were lighting those rose fireworks (the kind which spin and light up on the ground), putting them in a water balloon launcher and flinging them into the sky. While we were aiming for a river, this also meant we were aiming for some brush. Unsurprisingly, we eventually had one land short while still burning and started a bush on fire. We ran down and started trying to put it out with dirt. This wasn’t going well until we remembered we had a small container and a ready source of water (the river) and managed to douse the fire.
