Air density refraction

I just saw a video of somebody creating a curve in a fish tank, hiding an object below curve. Then pouring sugar into the water which made the object appear to rise above the curve. I have no rebuttals here but looks like proof of downward refraction ?

sugar water refraction has nothing to do with density. lol and we can't evaluate a video we didn't see. 🤷‍♂️
