Sorry, no sale. The cement supports are clearly visible until they get too small and unfocussed, but you can still see their distinctive grey tone all the way the the far shore.
Here's another 1 minute vid that squashes it:
As I said, there are hundreds of vids around. You can try it yourself. Get a decent zoom camera and a tripod, find a local lake, use Google Earth to measure between 2 points with a landmark on one side (of which you can check the height), off you go, measure your tripod/ camera height, do some filming, run it through the earth curve calculator, and presto! standard GE disproven.
I've been involved in FE since 2012, and geocentrism since 2008. This has all been done to death.
Have a look at the Lake Balaton laser experiment, where laser light was visible at 40km from a height of 1.5m. It's a highly technical experiment and you'd do well to actually research this stuff rather than shooting your mouth off about some random photo plucked from Google images, just because you're too afraid to confront the possibility that you've been fooled all these years.
