Shape Reconfigurable Liquid Metal Video
Researchers at NC State have developed a new method to control the interfacial energy of a liquid metal via electrochemical deposition (or removal) of an oxide layer on its surface using ~1 volt. Liquid metals have very large surface tension and therefore typically adopt a spherical shape. Surfactants, like soap, can lower the interfacial tension between two dissimilar liquids (for example, water and oil), but have negligible impact on the large interfacial tensions of liquid metal. Unlike conventional surfactants, the approach here can tune the interfacial tension of a metal significantly (from ~7x that of water to near zero), rapidly, and reversibly using only modest voltages. These properties can be harnessed to induce new electrohydrodynamic phenomena for manipulating liquid metal alloys based on gallium, which may enable shape-reconfigurable metallic components in electronic, electromagnetic, and microfluidic devices without the use of toxic mercury. The results also suggest that oxides—which are ubiquitous on most metals and semiconductors—may be harnessed to lower interfacial energy between dissimilar materials.

Obligatory Terminator post.

Joking aside, that's pretty cool.

Holyyy Spaghetti !!
Have the Cyberdyne Systems been founded yet?

This is pretty impressive, and nice to see gallium have a purpose that takes advantage of its liquid state properties. I'll be interested to see what they can manage to release with this, because as of right now I don't see any use. If they gave examples during the video, I didn't hear it since I don't have speakers on my office computer.

Never before have I seen a video with such a completely inappropriate musical choice.
Try playing it on your phone whilst on a train or sipping coffee with the music turned up, and watch as people give you 'that look'.

That's awesome.
