'We could make photons interact inside that cavity and in experiment we were able to actually create a fluid of light, so interacting photons with a mass which is very similar to any other fluid. In particular, because the mass is so light, it was possible to achieve quantum effect such as, for example, superfluidity at very high temperatures. '
