A lab at Purdue University has created the world’s whitest paint. The scientists say the paint is so white that you might not need air conditioning. The paint was made in a bid to mitigate against global warming. Unsurprising, the Guinness World Records now recognizes it as the whitest paint ever created. Professor Xiulin Ruan, a mechanical engineer at Purdue University in Indiana, noted that the project commenced about seven years ago to mitigate against climate change and promote energy conservation. They hoped to achieve this by creating a paint that reflected sunlight to the largest extent possible.
