How to keep children entertained during this period of confinement, while learning complex concepts like car aerodynamics?
Ángel Suárez, SEAT engineer, made a short video, with his own children, in which he performs a small experiment that allows him to find out which rounded shapes offer less aerodynamic resistance.
To do so, the experiment consisted of trying to blow out a candle with a hair dryer, where the air flow from the dryer is interrupted by an object that simulates a car. The first object was a milk carton—a cobblestone—the second a milk bottle—a cylinder.

The results are clear. The air projected by the dryer as it hits a wall when it hits the cobblestone, so it changes direction upwards, without the candle being hit by the air flow. When using the cylinder, the air is able to get around its softer shape and hit the candle, extinguishing it.
It doesn't stop there. Ángel Suárez has shared more experiences with his children on his Linkedin account, many focused on automotive aerodynamics, which are as much entertainment as didactic.
