A TUNNEL — You know what sounds to expect when there's an explosion in a tunnel; the movies taught us that.
But do you know what you'll see if there's no fire and debris like a movie explosion with so much CGI it hurts?
In this video, a few workers are standing in a tunnel, ready to detonate a controlled explosion as part of some sort of unidentified infrastructure project.
"Fire in the hole!" One man yells before pushing the button to make the boom. And a very big boom it does make. A boom that echoes and sounds over and over again. It's the kind of boom that shakes your bones even though you're just watching a video.
But something else also "echoes" up and down the tunnel — a visible "cloud" of the sound. What you're actually seeing is compressed airwaves, or shockwaves, moving up and down the tunnel in its own echo-like pattern.
Experiencing both the sight and the sound together is a jaw-dropping experience in video form.
But imagine what it's like to feel the pressure and vibrations of tunnel shock as well. This second video may help. It shows another group of workers in a tunnel, waiting for an explosion. They are not at the detonation point, so their experience is a little different.
They can hear the tunnel shock coming like an earthquake a few full seconds before the sound hits, giving them time to cover their ears. The giggles, grins, and shouts afterward are likely a sign that the adrenaline of the experience is real.
It party feels like it would be a fun carnival ride experience, and partly feels like, "Nope, I don't need to feel that, my bones are fine as is."
