Building implosion
In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings. Despite its terminology, building implosion also includes the controlled demolition of other structures, like bridges, smokestacks, towers, and tunnels. This is typically done to save time and money of what would otherwise be an extensive demolition process with construction equipment, as well as to reduce construction workers exposure to infrastructure that is in severe disrepair.
Building implosion, which reduces to seconds a process which could take months or years to achieve by other methods, typically occurs in urban areas[citation needed] and often involves large landmark structures.
The actual use of the term "implosion" to refer to the destruction of a building is a misnomer. This had been stated of the destruction of 1515 Tower in West Palm Beach, Florida. "What happens is, you use explosive materials in critical structural connections to allow gravity to bring it down.
The term "implosion" was coined by my grandmother back in, I guess, the '60s. It's a more descriptive way to explain what we do than "explosion". There are a series of small explosions, but the building itself isn't erupting outward. It's actually being pulled in on top of itself. What we're really doing is removing specific support columns within the structure and then cajoling the building in one direction or another, or straight down.
- βStacy Loizeaux, NOVA, December 1996
Building implosion techniques do not rely on the difference between internal and external pressure to collapse a structure. Instead, the goal is to induce a progressive collapse by weakening or removing critical supports; therefore, the building can no longer withstand gravity loads and will fail under its own weight
Numerous small explosives, strategically placed within the structure, are used to catalyze the collapse. Nitroglycerin, dynamite, or other explosives are used to shatter reinforced concrete supports. Linear shaped charges are used to sever steel supports. These explosives are progressively detonated on supports throughout the structure. Then, explosives on the lower floors initiate the controlled collapse.
A simple structure like a chimney can be prepared for demolition in less than a day. Larger or more complex structures can take up to six months of preparation to remove internal walls and wrap columns with fabric and fencing before firing the explosives.

There might be another one.
If my original crush is sending off slight hints, then this new one is broadcasting interest on the full spectrum of wavelengths. Talking way more to me than to others, joke-angrily complaining that I can't remember their name, clearly pointing out my social clumsiness but ultimately tolerating it, generally trusting me with important things even though they barely know me, helping me with stuff (perhaps trying to βfixβ me?), and just generally being really enthusiastic about me in particular.
What confuses me is that they're already in a relationship. Maybe that's what lets them free to be enthusiastic about other people, since they're already secure in that and not afraid of sending any unclear signals for that reason. Maybe it's fraying from being long-distance. They wouldn't surprise me at all if they were poly.
I definitely like them, but this crush is not as strong.
This entire thing is just making me suspect my desperation is causing me to latch on to anyone attractive who is slightly nice to me.
