The exhibit is titled `Leonardo da Vinci - Observa, Questiona e Experiment` and is located on the Praca de Gomes Teixeira. The exhibition occurs from September 8th to October 6th, 2021.

Three centuries later, with the arrival of steam, the propulsion system became more efficient and paved the was for the success of the Mississippi paddle boats.
