Okay, this video has been popping up all over my Facebook feed. At first I just skipped it and then I finally broke down and watched it. This invention is wild, and it's called a "Fish Cannon." Don't worry, it doesn't shoot fish into the air. In fact, this fish cannon helps native fish pass over dams in seconds rather than days according to the video below. The fish travels in a soft tube from the water below a dam to the breeding grounds above. You have to see the video below.
