Summary:"It is possible to measure the Earth's radius -- armed with only a stopwatch, a meter stick and a sunset or sunrise! Keep in mind; this is a demo, not a Fermi-like laboratory investigation. That said, this will yield surprisingly """"accurate"""" results given the kids don't mess up on the two measurements they do have to take."
