Need to convince a Flat-Earther than the Earth is round? Here are some basic at-home experiments to show that the Earth is round. Unfortunately, all Flat Earth conspiracy theorists likely won't all be convinced, but maybe some curious ones will be.
Presenting the second installment of our "Bad Answers" Science Q&A series, answering questions from our social media followers! Instagram user @mrssisypeanskeptic asks, "How Do We Know the Earth is a Globe?" and Astra talks about shadows on the moon, several experiments you can do yourself, and some nerd from ancient Greece.
