It's a real disappointment when you arrive back home with your takeaway dinner, to find it gone cold. You obviously don't want to put it in the microwave, because that only makes matters worse.
Luckily, a genius on twitter shared a clever hack to avoid this problem. Eric shared two pictures on twitter; one showing the seat-heating on full - and his food safely, and still warm, in the passenger seat.
People seems to me impressed by this hack, and there has also been several recreations. Someone also showed us what to do if you need to keep something cool? It's really no problem at all!
Internet, what would we have done without you?
