Over at Hayward Gallery in London, something is a-brewing. Chemical landscapes and morphing organisms float through glass tanks and a large-scale, immersive video installation, in an exploration of the delicate, ephemeral qualities of the natural world. They’re the work of Moroccan artist Hicham Berrada, a kaleidoscopic exploration of the magic of scientific processes and natural phenomena such as heat, cold, magnetism and light. The exhibition is open until 18 August.
