"FIRE IN THE HOLE."
Shockwave Traveling Back And Forth In Underground Tunnel Following Explosion

Note: Keep your volume in check.

In how to piss off the Ninja Turtles news, this is a video of an intentional detonation in an underground tunnel that causes a shockwave to travel back and forth along the length of it because it has nowhere else to go. Sounds like me on any given Friday night! I could use a hug. Also, there’s no way to really prove these are actually shockwaves and not the ghosts of farts desperately searching for the tunnel that leads to the afterlife.
