If the weather means your car is hotter than the seventh circle of hell this summer – you might be interested in this DIY top tip from an Arizona driver and content creator to help you stay cool.

The simple hack from ilovemegapixels went viral, amassing over 254,500 views on TikTok.

It’s cheap and easy to DIY using just aluminium foil to lower the car’s temperature.

The best part? People who’ve tried it say that it really works.

While leaving windows open – even slightly – to vent heat in summer can help, it may increase the possibility of theft or break-ins.

This TikToker seems to have a solution to help you stay cool.

In the video, he pulled open the car’s sunroof to reveal that he’d placed a sheet of aluminum foil or reflective sunshade under his car’s sunroof. Why? To block sunlight.

“Little tip for you,” he simply said before closing it.

That might seem counterintuitive, as aluminium is commonly associated with keeping food warm. But it turns out that he could be onto something.

The reflective surface of the foil reflects sunlight. And as result, it reduces heat buildup inside the car, especially through the glass of a sunroof.

Plus, it’s nowhere near as bulky or indiscreet as a windshield shade or foam insulation.

In fact, when another driver gave it a go, he reported a significant temperature drop of up to 30°F in the interior roof area using an infrared thermometer.

It might have been useful when a video emerged of cars in China becoming ‘pregnant’ in a heatwave.

While some solutions, like tinted windows or an entire roofless Lambo, are more cost-intensive, this hack is cheap, using materials like aluminum foil, home insulation, or heat-reflective mats.

Easy to cut and slot into your sunroof area without tools or permanent modifications – it’s doable even for the most DIY-averse driver.

However, it has nothing on these artists who turned unsuspecting cars into DIY masterpieces or this one who turned his couch into a car.

If your home is heating up too, you can also use it for home windows to reflect sunlight and reduce indoor heat – perfect for the TikToker’s home state of Arizona.

While some comments raised concerns about potential glass damage, tempered automotive glass is designed to handle heat.

The majority of commenters were delighted at the prospect of being able to stay cool in the heat this summer.

“I live in Texas! I will try ANYTHING!!!!!!!!” one said.

“Thank you! From an Arizonian,” another commented.

“Much appreciated – I’ll try that,” said a third.
