Floating world

摘要

THESE black balloons show just how easily scientific principles can be transformed into art. To create his work, Lithuanian artist Tadao Cern tied pairs of balloons together and filled them with gases of different densities. The ones floating at the top contain helium and the lower ones air. Each pair is sealed in a glass tank filled with a mixture of helium and air. The relative densities of the gases inside the balloons and inside the tanks allow the balloons to float, one above the other, seemingly fixed in place. The effect is strangely disconcerting.
