It's summer, and if you live anywhere the sun shines,
science dictates that it gets stupid hot inside your car when it's closed up
and baking in the sun. According to this Japanese video, rolling down one
window and opening and closing the opposite door a handful of times will
quickly and effectively cool down a hot car.
The video's only two and a half minutes, but unless you
understand Japanese (or can read the Chinese subtitles), jump straight to the
1:52 mark to get the picture. Reddit user binarysolo offers this loose
translation:
Roll down a window on a side of the car. Let's go with the
driver's side window. Go to the opposite side door (in this case, passenger side)
and open/close it ~5 times. Just do this normally.
SCIENCE: What we're doing here is to help circulate air by
drawing the hot air out from the opening/closing door, and causing the cool(er)
air to enter the car. So... be careful. Don't accidentally jam your hand
against the door. Also, do this when nobody is next to your door so you don't
slam it into them.
In the video demonstration, the temperature outside the car
was 86.9 F, and the car went from 106.8 F to 92.3 F. Your mileage may vary, but
the Reddit users who tried it seem to be reporting good results.
We've looked at how to cool a hot car with some simple
thermostat management, but, unlike this simple trick, you still have to suffer
the heat of your oven-like car while you wait for the A/C to kick in. Give it a
try and see how it worked for you (or how you quickly cool your car).
