Welcome to the return of the fish tank. In this video I show you how I create a looping, seamless “boomerang” transition where a product drops, bounces, and morphs into the next color—using nothing more than a fish tank, a camera/phone that shoots slow motion, and editing software. The big capture tip: don’t use tap water. Tap water gets cloudy from minerals, so I use distilled water for that super clean, crispy look, then I squeegee and clean the glass to kill bubbles and smudges before rolling. Once I’ve got clean drops (I shot four bottles and strategically flipped every other one upside down), I stack clips in a tall custom timeline, rotate/position them to line up, and use a quick shape mask + feather to blend between colors. Then I color grade (I’m crushing shadows to hide the tank, popping highlights/saturation, and nudging hues so green doesn’t go yellow and red doesn’t go orange), compound it, and bring it into a vertical project for mobile. From there it’s all about timing: I speed ramp the whole thing, slowing down at the top/bottom for impact, then track the bottle to keep it centered. To spice it up, I add motion blur on the fast parts, plus subtle overlays like film glitch, film burn (to hide loop stutters), and film grain for extra punch.
