On 29th September, the QPL team took part in Explorathon 2018 with their ‘Atomic Architects’ exhibit at the Lyell Centre, Heriot Watt University. Visitors were able to peel off layers of atoms using sellotape before viewing their efforts under the microscope. They also saw Moiré fringes in action on our spinning model of two layers of atoms, which was especially appreciated by the younger visitors to the stand. Our younger visitors also loved seeing colourful thin-film interference effects in soap bubbles held up to a white light lamp. Thanks to all our volunteers for the day, everyone had a lot of fun!
