Here in the NYC area, we are currently experiencing what may become the hottest week of the year. 
Summer has always been my least favorite season because I loathe the heat, humidity, and yes, even the longer days.
As anyone who has traveled in a vehicle during the peak of summer can attest, one of the worst things about the heat is getting into a car that has been baking under the sun for hours. So this morning, I was delighted to find the following video on Reddit — by rolling down the window on one side and opening and closing the door on the other side 5-6 times, you can instantly cool down the interior of a car!
The proof is in the video: the outside temperature reads 30.5°C (86.9°F) while the temperature inside the superheated car is a sweltering 41.6°C (106.88°F). After performing the window and door trick, the temperature drops down to a bearable 33.5°C (92.3°F)!
I am sure that there is some cool scientific explanation behind this, but I’m afraid you will have to uncover that yourself. 
Although I usually like to stay within the confines of the wonderful invention that is central air during the summer months, I can’t wait to try this out the next time that we are out!

Oh, wow, what a neat trick! I’m definitely sending this to my parents and sister, who as NJ burb dwellers use the car more often than I do
Yeah its cool, except for the fact it doesn’t work
At least the one time I tried it, it didnt cool down at all.
hope other people have better luck!
Sorry it didn’t work for you…but a friend told me that she tried it just now and it worked for her!
I cannot thank you enough for posting this! I can’t wait to try it out and tell everyone about it. Any cheap ways to beat the heat are important for survival!
I will definitely try this. The a/c in my car has not been working well, which makes it pretty uncomfortable after it’s been sitting out in the sun. If it works, this could really help!
Ha, I am your opposite! I love heat and humidity, and I love getting into a steamy car that’s been baking all day. Honestly, I look forward to it. I know, I’m insane.
What is WRONG with you?
Just kidding. I know everyone has different preferences. I have a friend who is like you, and dreams of moving to Florida one day! (Me? I actually wouldn’t mind living in Alaska!)
I’m like you, Andrea!! Especially I’ve been in a mall/big store/office where it’s FREEEZING. Feels so good to go from that to a nice warm car!
Wow, I’m definitely going to have to try this!
THANK YOU! I totally need this in Louisiana…my car is miserable for the first 10-15 minutes after work!
I have tried it on several different occasions now and suggested it to my friends. I have to say, we love it! It works for us and makes it a little easier for the AC to cool down the car.
