Peut-on détruire un pont en marchant dessus en cadence?

S1 E56
·
2016

It was a historical event dating back to 1850 that inspired Agathe, David, and Vincent to undertake this new experiment. Napoleonic soldiers are said to have destroyed the Angers Bridge by marching across it. With the help of a marching band, will the test subjects manage to find the right rhythm to make the bridge resonate? It’s not certain that the structure will withstand our group of serial testers.
