The internet is going crazy over a 'salmon cannon' that shoots fish over a dam

The "salmon cannon" has been around since 2014, but Twitter discovered it over the weekend.

(CNN)Give Twitter a fish, and you feed it for a day. But teach Twitter about a cannon that shoots salmon through a tube, and you feed enough memes to make people forget about 30 to 50 feral hogs.

The internet is losing its collective mind over a video of Whooshh Innovations' salmon cannon -- yep, that's it's real name -- built to zip fish over hydroelectric dams that block their migration paths.
The video shows a man chucking a salmon into a tube. The translucent channel is suspended mid-air, and the fish's speeding shadow tells a harrowing story of a life in upheaval. On it goes, for what probably feels like years in fish time but is in reality only a few seconds, until the fish is spat out on the other side of a dam.
    Salmon swim up to the tube, which shoots them up to 22 miles per hour over a dam.
    People were immediately fascinated by the fish contraption, and they've quickly capitalized on the bizarre flying-fish machine.
    "pack my body in the salmon cannon and shoot me into the sun. i want to be among the stars," someone said, realizing the fish cannon's ultimate potential.
    Comedian John Oliver reminded everyone that he made his own version of the cannon on an episode of "Last Week Tonight" in 2014, when he "wooshhed" salmon onto Jon Stewart's desk at "The Daily Show."

    It doesn't hurt the fish, the CEO says

    What does the man behind the fish-flinger have to think about his contraption's viral fame? "It's sort of been outrageous how long this has taken to catch on."
    Whooshh Innovations CEO Vince Bryant said the video, created by streaming news network Cheddar, was stitched together with footage dating to 2014, when its first cannon was sold.
    The first system required workers to hand-feed fish into the tube to bypass the dam, but today's version lets fish swim into it themselves, he said.
    Not to be lost among all of the fish jokes is that fact that torpedoing a salmon several hundred feet in the air is a significant feat of engineering.
    The salmon are propelled by the differential pressure between the front and the back of the fish and sent into the flexible tube that expands to their size. Once inside, the fish are misted with water to keep them breathing. And within a few seconds, they've splash-landed on the other side of
