As a member of the American Chemical Society, I regularly get their issues of the C&EN Newsletters. As an addendum they have an item called “ Chemistry in Pictures”, which are always good fun. One in a very recent issue ( February 23, 2023) in particular caught my eye and since readership is restricted I consider it worth putting up here. It was created by Pichayut Tananchayakul, a PhD candidate in organic chemistry at Mahidol University, and is designed for teachers to use in the classroom with their secondary school pupils. It involves dissolving turmeric powder in ethanol and filtering to produce a yellow solution. Then the solution is poured into a glass of ethanol under black light to achieve the effect as shown in the image below. Obviously to be viewed by the pupils and not drunk!
