Summary
| Description |
Afrikaans: 'n Beker hou water met blou voedselkleurstof (boonste vloeistoflaag) en 'n baie digter perfluoroheptaan ('n fluorkoolstof) as onderste vloeistoflaag. Die twee vloeistowwe kan nie meng nie en die kleurstof kan nie in fluorkoolstof oplos nie. 'n Goudvis en 'n rooiknyperkrap is in die water geplaas. Die goudvis kan nie die digte fluorkoolstof binnedring nie. Die krap dryf by die vloeistofgrens met slegs dele van sy bene wat die fluorkoolstofvloeistof binnedring, en kan nie na die bodem van die beker sink nie. Muntstukke rus wel op die bodem van die beker. Die diere is uit hul penarie gered na die foto geneem is.
English: A beaker holds water with blue food dye (upper liquid layer) and a much more dense perfluoroheptane (a fluorocarbon) lower liquid layer. The two fluids cannot mix and the dye cannot dissolve in fluorocarbon. A goldfish and a red clawed crab have been introduced into the water. The goldfish cannot penetrate the dense fluorocarbon. The crab floats at the liquid boundary with only parts of his legs penetrating the fluorocarbon fluid, unable to sink to the bottom of the beaker. Quarter coins rest on the bottom of the beaker. Animals were rescued from their predicament after the photo was taken. |
