Researchers at Purdue University earned a Guinness World Record with an unusual development: the world's whitest paint. Xiulin Ruan, a professor of mechanical engineering at the West Lafayette, Ind., school, said the original aim of the project was to create a paint that would reflect sunlight from a building and thereby lower energy usage as a means of fighting climate change. The paint, which incorporates barium sulphate particles, reflects 98.1% of solar radiation, making the painted surface noticeably cooler than surrounding surfaces, Ruan and his team found. The paint was declared the world's whitest by Guinness World Records, which selected the record for inclusion in the 2022 edition of the Guinness Book of World Records.
For the record, the only thing whiter are my pasty white legs! Wonder how many people will use this paint for their homes?? And will they carry it at Sherwin Williams on Welcome Way...?
