Struggling with a boiling hot car during this heatwave? 🚗☀️ We’ve got an awesome hack for you, and it doesn’t even require cranking up the air con! 😎 A clever Cambridge University maths professor has shared how you can cool your car down in less than a minute using fluid dynamics—sounds fancy, but it’s super easy!
Here’s the trick:
1. Open the back window opposite your driver’s seat.
2. Rapidly open and close the driver’s door a few times.
This nifty move creates something called bulk flow, whisking away all that sweltering air and replacing it with cooler breeze. Hannah Fry swears by this simple hack, and it’s surprisingly effective—just a couple of tries, and your car feels blissfully cool again. 🙌
Pro tip: Covering your seats with blankets when you’re parked can help too, as they soak up the heat instead of the seats.
Give it a go and enjoy a cooler ride this summer! 🚙💨
