Are some liquids surface tension so high they can be confused for a solid object?

Answer 1

The surface tension of mercury is high enough that it could be confused for a solid object, depending how thoroughly you observe it. Like, small amounts of mercury will roll around like little balls and look like little solid balls to the naked eye.

Of course, it is a liquid, and minimal further examination would show that, but it could be initially confused for a solid. I’m not sure if OP meant it would confuse a careful observer, or it could fool someone, like in the sense of a magic trick.
