In that place where Barcelona meets the mountain, not far from Park Güell, there is a modernist building that houses the CosmoCaixa, a science museum for kids and adults alike. When you enter, you slide down a ramp that represents a timeline of history, from the creation of the universe to present times. This path leads you to a magical and astonishing underground world. The purpose is to introduce children to science through their own experience: playing, touching, observing gadgets, animals and inventions.
