Last night some friends and i went to toss an artillery shell (firework) into a friends yard, i lit the fuse threw it out the sunroof, it got caught rolled back in and exploded in my seat. Besides the burns and blood the damage to my body wasn't too bad, my friends car's ABS system was blown to pieces apparently (how necessary is ABS?), but the main thing im worried about is today when i woke up my equilibrium is completely jacked, also i can't hear anything out of my left ear. Any thoughts to why its messed up?
