Une voiture peut-elle exploser comme au cinéma?

S1 E73
·
2016

The atmosphere is explosive in the lab! Agathe, David, and Vincent are convinced it’s impossible to blow up a car like in action movies. How could a mere trickle of gas and a match be enough to cause that much damage? Our dynamic trio will find the answers by looking into the composition of gasoline and the physical and chemical properties of its combustion. For the ultimate experiment, Vincent has donned his secret agent suit. His mission, should he choose to accept it, will be to blow up the lab's car! A fireworks display… with or without a gadget?
