Children have discovered an ingenious new way to bunk off school. All you have to do is to pour a soft drink on a lateral flow test and watch a positive result emerge within minutes. The trick is explained in videos circulating on TikTok, which have been viewed millions of times.

But scientists are finally on to the cunning youngsters. Chemist Mark Lorch has been experimenting to discover exactly how this trick works. And parents out there should pay attention: he’s even found a way to check whether a test has been tampered with.

Other scientists have investigated the future of buildings. As the effects of climate change become more severe, many structures face risks ranging from shaking and cracking to termite invasions. And actor Michael Sheen says there is a class problem in the arts. He’s not wrong, and he’s doing something about it.
