REVOLVE had a very successful participation in the Science in the City Festival which took place in Toulouse (9th-14th July 2018) as part of the 8th edition of the EuroScience Open Forum (ESOF). REVOLVE fellows together with volunteers from the three institutions showcased their latest innovations and proposed scientific challenges to visitors in a friendly and interactive Fun Family Day. The presented open session named ‘REVOLVE – Waves: Radio and Space’ allowed attendees of all ages to take part in a series of applied engineering experiments ranging from making your own speaker, setting up your own radio link and making music with the wave of a hand through interference of electromagnetic fields. All public actively engaged with the team and had alos the opportunity to see real satellite components. Being the largest interdisciplinary science meeting in Europe, the event offered a unique framework for interaction between engineers and the general public.
