The buckets just aren't big enough.
Even though the military can use some of its old advancements as hand-me-downs to the general public, more often than not it's stuck with massive amounts of rusting technology made obsolete by peace, or more likely, better technology. So what is everyone supposed to do with all the leftovers?
The solution could be as simple as finding other questions that this technology can still answer. Granted, the new uses for old technology are not always benign. These were, after all, weapons originally designed to tear, poke or melt people to death, so some of the solutions are equal parts evil and ingenuity. Still, it's nice to see people recycle.
5Coming Home to a Nazi Bunker
After all the bodies and bullet casings were picked up from WWII and the reconstruction of small towns had started, Western Europe still had the problem of dealing with massive Nazi bunkers swelling out of the ground in cities and coastlines across the continent like concrete warts. The worst inflammation was, of course, in the heart of Germany and destroying something that was intended to withstand bomb attacks is understandably difficult and expensive. So for the most part, everyone just learned to tolerate them.
But within the last few years, Germany has started repurposing the old bunkers as houses and even as apartment complexes. Logically, it makes perfect sense: The bunkers are generally at the heart of most cities, and the design requires little upkeep because they are built to last longer than even pyramids. Aesthetically, however, there aren't a lot of options for giving towers of death a warm touch.
Architects have come up with creative ways to carve out windows, build around the ugliness and generally dress up a blister as something other than a blister.
To their credit, some of the designs are really ingenious combinations of modern architecture and disaster-preparedness. In a few cases, it is nearly impossible to tell that it was ever a military bunker at all.
Several of them could easily be confused with hastily-made, postmodern architectural decisions, which, in the greater context is much easier to look at and live in than a monument to the one of the worst atrocities in human history.
4Chinese Police Carry Crossbows
The crossbow revolutionized warfare in the 4th century, but it became obsolete when militaries around the world discovered that gunpowder could do the same job a lot better. As a result, the crossbow became a novelty item, purchased only by weapons enthusiasts or hunters who ran out of exciting ways kill stuff.
But after collecting dust for centuries, China recently picked up the crossbow once again and handed it to their police officers.
"Your tags are expired."
In cities around China, every level of law enforcement is rediscovering the advantages of a crossbow, from traffic cops to special units. In Xinjiang, riot police carry crossbows instead of beanbag guns and smoke bombs because China has no interest in messing around with nonlethal crowd deterrents when terrifying, medieval battle weapons are just as effective.
"What's up now?"
Before anyone tsk-tsks the Chinese government for shooting at crowds with crossbows, you should know that these aren't the usual burning-cars-and-looting riots we're used to seeing. Granted, China has a bad history with breaking up mobs, but in this case the use of violence is warranted; China has a pretty significant terror problem on the borders of Pakistan. The East Turkestan Islamic Movement is spilling across the border and introducing China to suicide bombing and improvised explosives. The primary advantage of using crossbows instead of guns against these attacks is that they allow police to shoot and kill anyone carrying an explosive while lessening the risk of detonation. So after thousands of years, the crossbow is coming out of retirement as a means to stop brand new bombs. As an added bonus, China is also fully prepared now for a full-scale vampire attack.
