Last week a video of scuba divers hunting invasive lionfish with a Glock 17 went viral. After being flooded with questions, the creators responded with another video explaining how their underwater suppressor worked and why they needed it. Please forgive the rifle cartridge in the animatic, we don’t know why they didn’t just use a bullet either. The image isn’t to scale anyways, it seems like it’s just there to help illustrate the concept.
