Explosions, Fire in Space....YEAH

Ok so you have space flyers scrambling, setting out all sorts of munitions. Why not use the space debris as reflectors. As space junk is floating by causing all sorts of manuevers for the pilots have a weapon that can bounce once off of the debris hitting a target then exploding.

Example:
Nazi craft is targeting enemy craft there is pieces of a recently launched rocket nearby A canister is launched by the Nazi craft that deflects off of the space junk at a trajectory that hits it's target. causing the enemy craft to impolde upon itself.

Also looking at the Norway Sky spiral might give some ideas as to using advanced technology, and would give off shock effects to the viewer. Like the battle in space is causing all this phenomina on Earth.

Example: A hit craft goes into a spin losing a spiral like gas into space then finally imploding. From Earth view it looks like the Norway Spiral.

Also another type of explosion you could use is transient black hole effect.

Example: A canister containing dark matter is shot with armor piercing capability. It hits and imbeds itself into a ship, a timer goes off and the dark matter chamber breaks disolving the ship into nothing causing an area to avoid by future space fights.
