The heavy object is submerged but not touching the bottom of the container. That I hope is clear enough for everyone.
A heavy object will not be affected by changes in the liquid voyancy which is what's being measured
that's under the impression the object is sitting on the bottom or just not understanding what buoyancy force means? If liquid density (specific gravity) changes, buoyancy force changes. You should check some reference before "brainstorming". My understand of the word is that you think of some random stuff but still they have to be correct. Otherwise it's hard to differentiate it from bullshitting.
