quantum mechanics experiments with condensates ,a state of matter resulted from super cooled particles that have the same energy and can occupy the same quantum state, thus the same place in space (leading to waves of energy such as radiations and light).At this state quantum effects happen on a larger scale.Experiments with rubidium condensate led to implosion beyond detection level and then to explosion (similar to a supernova).experiments also managed to slow down light pulses to very low speed
