Decorative circuit round which balls move - being made of pipes joined together and containing fluids with three different densities in which balls are submerged

摘要

The circuit (3) is formed from groups of successive pipes (8,9), assembled in any order. The balls (4) move round the pipes whose cross section is slightly larger than that of the balls. The balls are submerged in three fluids (5-7) with different densities. The first fluid (5) has a density greater than that of the balls and is in the base of the structure. The density of the second fluid (6) is lower but is greater than that of the balls. The density of the third fluid (7) is less than that of the balls.
