Construction began, but was interrupted by the outbreak of World War II. Resuming work in 1945, he completed the bubble-shaped cockpit that maintained normal air pressure for a person inside the capsule even as the water pressure outside increased to over . Above the heavy steel capsule, a large flotation tank was attached and filled with a low density liquid for buoyancy. Liquids are relatively incompressible and can provide buoyancy that does not change as the pressure increases. And so, the huge tank was filled with gasoline, not as a fuel, but as flotation. To make the now floating craft sink, tons of iron were attached to the float with a release mechanism to allow resurfacing. This craft was named "FNRS-2" and made a number of unmanned dives in 1948 before being given to the French Navy in 1950. There, it was redesigned, and in 1954, it took a man safely down . Piccard and his son, Jacques, built a second bathyscaphe and together they dove to a record-breaking depth of in 1953. Auguste Piccard died on 24 March 1962 of a heart attack at his home in Lausanne, Switzerland; he was 78 years old. P-Funk  P-Funk (also spelled P Funk or P. Funk) refers to the repertoire, musical style, and/or group of performers associated with George Clinton. The term is variously known as an abbreviation of Parliament-Funkadelic, "Psychedelic Funk", "Pure Funk", or "Plainfield Funk". The P-Funk groups had their heyday in the 1970s and continue to attract new fans thanks both to the legacy of samples they bequeathed to hip hop and the live shows that the bands continue to perform. Their music was very aspirational, which is symbolized by their Mothership that has since been acquired by the Smithsonian. Notable P-Funk albums include Funkadelic's "Maggot Brain" and Parliament's "Mothership Connection". The differing styles of these albums showcase the wide range of P-Funk's music. ""Maggot Brain" was an explosive record" of Jimi Hendrix inspired rock while "Mothership Connection" was an "album of science-fiction funk." While this rock/funk differentiation is what normally separated Funkadelic from Parliament, the bands consisted of many of the same members and performed live on tour together. Hence, the two groups are often described under the one moniker Parliament-Funkadelic.
