Density question - please help!

[From: ] [author: ] [Date: 13-02-20] [Hit: ]
why does the mercury not move down through the copper?This is a question from grade 8 science, so must not be a complicated answer-The copper is in the form of a solid metal piece. It is able to support the mercury. The liquid mercury cannot penetrate the solid copper.-the density may be mistake recheck it.......
Liquid mercury (13.55g/mL) is denser than solid copper (8.92g/mL). When a drop of mercury is placed on copper, it stays on the top. If mercury is denser than copper, why does the mercury not move down through the copper?
