Am I the only one who tested the horizon with a laser pointer at the lake?

So last weekend I grabbed a cheap green laser from Amazon and drove out to Lake Michigan. I set up at the beach and aimed it across the water at a boat about 3 miles out. According to flat earth logic, the beam should have stayed straight and hit the boat's hull just fine. But nope, the laser lit up the sky above the boat, not the boat itself. The curvature blocked it just like basic science says. I even double checked with a buddy on that boat via phone to confirm he saw nothing. Has anyone else tried a simple experiment like this and got a reality check?

Wait, you actually proved the curvature with just a laser pointer and a friend on a boat? That's wild because I used to be one of those people who watched flat earth videos and thought maybe there was something to it, but this experiment makes it super obvious the math checks out. I never tried it myself but seeing your results kinda flips the script for me.

Yeah I was in that same boat @fiona_johnson82, no pun intended. Watched a ton of those flat earth videos and it all sounded convincing until I actually went out and tried the laser test myself with a buddy. Seeing the beam drop at exactly the distance math predicted just kills any doubt pretty fast.
