Thanks to Ronaldo for sending this one to us.
The video says this is a New Year’s Eve celebration in Syria. More importantly there is a considerable amount of anti-aircraft tracer rounds being fired out into the night sky. I wonder what happens to those rounds? We all know the potential problem of firing ammo into the air can possibly do damage when they come back down. But what about anti-aircraft tracers? Are they similar to standard tracers in that they have a special coating on the round? Do those rounds have the mass to do damage when they fall?
