Experiments frequently come with surprises. In this talk, I will describe the serendipitous observation of Bose fireworks, a fast, seemingly random emission of atoms from a periodically driven Bose-Einstein condensate. This emission originates from collective scattering of atoms, which undergoes exponential bosonic amplification. Cascaded scattering results in a complex jet structure resembling those observed in high-energy collisions of heavy ions. Finally we show that the evolution of the condensate well approximates the Rindler transformation in Minkowski spacetime. The fluctuations of the emission thus simulates the Unruh radiation, the manifestation of quantum fluctuations in an accelerating reference frame.
