The sound of popping bubble wrap, the texture of sand or the sight of a familiar plastic chair can transport us back to moments from childhood that otherwise seem lost to time. These ordinary objects are at the heart of Emirati artist Reem Al Mubarak's new solo exhibition, which explores memory, play and the experiences that shape who we become. What We Left In The Sandbox opened at Rizq Art Gallery on Abu Dhabi's Reem Island on Friday.
