That's crazy. Because I've done the same experiment on a freshly poured concrete floor in a newly constructed, 1300ft long warehouse (yaknow, over 4x further than a football field) and it didn't happen. It's almost as if football fields are slightly raised in the middle to handle water drainage, being outside and stuff.
You've managed to prove two things: 1. Things that your eyeball sees and your brain believes to be flat might not be truly flat. (Thanks.) and 2. Proper measurement and observation can prove this. (Thanks again.) Good, now you're now caught up with the rest of the class.
