An Australian man claims he cooked an entire pork roast using just his car. According to a post on his Facebook page, Stu Pengelly decided to do the experiment on a scorching day in Perth. He says it was over 102 degrees Fahrenheit outside,and he left the food in his front seat for 10 hours. He later shared video cutting into the fully cooked roast and eating a slice. With the heatwave continuing across the county, he may cook other dishes in the foreseeable future.
