  In 1919, Eddington and Dyson led two famous expeditions to measure the
bending of light during a total solar eclipse. The results of this effort led
to the first experimental confirmation of Einstein's General Relativity and
contributed to create its unique and enduring fame. Since then, similar
experiments have been carried out all around the world, confirming the
predictions of the General Relativity. Later, developments in radio
interferometry provided a more accurate way to measure the gravitation
deflection. We believe that - after more than a century - starlight deflection
caused by the Sun's gravity still represents a simple and intuitive way to
introduce high-school students to General Relativity and its effects. To this
aim, we gathered measurements taken during eight eclipses spanning from 1919 to
2017, and we created a single dataset of homogeneous values. Together with the
whole dataset, this article provides a blueprint for a possible group activity
for students, useful to introduce the theory in physics classes with a playful
approach.
