For years it's been rumoured that, when the weather is really hot, you can actually cook an egg outside in the UK. With the recent heatwave having sent temperatures rocketing in the UK over the past few days, one man decided to see if the theory was actually true.

Ishan, known on TikTok as ishxn.a, wanted to see if his eggs could really cook sunny side up during the scorching weather over the past few days, and he was left completely floored by the results. When he carried out the experiment, he said it was around 33°C in London, so he was keen to see what would happen to his egg.

In a clip posted online, he said: "I want to know if I can fry an egg using only the sun. So, of course I have to put some oil on to my little saucepan to help it fry a little bit because, listen, the last thing I want is for an egg to stick to this pan.

"Of course, I had to do the one-handed egg crack, but I am so intrigued to see if this actually works or not. So let's come back in an hour."

He went back to the pan 60 minutes later and explained the yolk had "popped" for some reason. There wasn't much of a difference, so he decided to leave it cook for an hour longer.

After two hours had gone by, he admitted the egg wasn't looking good "at all". He did notice some whitening, which he thought was a start, but he decided to let it cook for an extra hour.

However, this didn't do much good as, three hours later, he thought it looked a bit of a "state." He said it looked watery, and the yolk didn't appear to be that great either.

In conclusion, it led him to say he doesn't think you can fry an egg during a heatwave, but it was a fun experiment to try out. Naturally, dozens of people commented after he posted the video.

One said: "That egg is nothing that I expected." Another wrote: "Look how thick the pan is though."

A third replied: "Bro has got too much time on his hands." Meanwhile, a fourth also commented: "Put it in a car."

Can you really cook an egg using the sun?

According to reports, it is technically possible to cook an egg in a heatwave during extreme conditions; however, it can also be unlikely, as you need really hot weather to do it.

Eggs need to reach around 158°F to cook and, even though heatwaves can get very hot, they usually don't reach that temperature on surfaces like pavements or car dashboards in the UK.

Eggs need to reach a certain temperature to cook. The whites begin to set around 144°F (62°C) and the yolks at 149°F (65°C).

Areas like sidewalks and car dashboards can get super hot during heatwaves, meaning they have the potential to reach high temperatures needed to cook an egg. However, these temperatures are not always consistent or guaranteed.

Also, it's important to note that even if an egg can be cooked in the heat, it's not recommended due to potential safety issues with bacteria growth at warm temperatures.
