SUMMARY
The discussion centers on the question of where a body weighs lightest, concluding that it is in cold water due to the principle of upthrust. The participant argues against the provided answer of "cold oil," asserting that oil typically floats on water because it is less dense. The key takeaway is that buoyancy provides an upward force, which does not change the actual weight of the body but affects the perceived weight in different fluids.
