An curved arrow pointing right. You definitely shouldn't mess around with mercury, but if you want a safe, similar, tactile experience, a metal called Gallium is widely available online.

Indeed, in the original communication of its discovery to the French Academy, it was described as a new liquid metal, similar to mercury; but on touching with a fragment of solid gallium a portion ...

"The process includes a few steps. First, pressing a drop of liquid gallium over the target substrate and freezing it to solid state, leaving a thin solid gallium film. Second, heating it rapidly." ...

The research, led by a team from China Agricultural University, focuses on developing a synergetic cooling and charging strategy using a gallium-based liquid metal flexible charging connector (LMFCC).

A recent study published in Engineering presents a novel approach to address the challenges of high-power direct current fast charging (DC-HPC) in ...
