One of the many cool things about weapons and ammunition is how entertaining they are to watch. Tracer bullets are a good one, especially at night, accompanied by green, red and blue flares. Try being on magic mushrooms for that extra tripped-outness. Explosions are pretty great as well. Mix plastics with household detergent to get a cool pyrotech explosion. And this plane with its decoys to fool heat seeking missiles looks like a fireworks display. Who knew that war and death could be so much fun?
