5 LIFE HACKS BASED ON SCIENCE

With the car life hack, some fluid mechanics to the rescue perhaps?

So here's what I've been observing. I'm not sure if it's true so I would appreciate people helping me to test it out. Anyway I realise that a car tends to cool faster if you opened windows which are diagonally opposite (front left and rear right, or vice versa), as compared to opening all the windows. See, in opening all the windows, the air flow is turbulent, and not much air that comes into the car is actively forcing more air out of the car. However, my theory is if you were to open only diagonally opposite windows, whatever air that comes in from the front window immediately pushes air out of the rear opposite window(while driving, of course). The air that's pushed out in turn sucks more air in from the front thanks to the negative hydrostatic pressure created.

Were you to open both windows on the same side it would be akin to blowing over a cup - only a tiny fraction of the air you blew over the cup's mouth actually goes into the cup and forces air in the cup out. The same would happen if you opened all windows in a car.

Again, would love to see someone test this theory and confirm (or debunk) it.
