Gallium sound waves

Thump Identity:

The usage of the Cymatic Gallium instead of the water pools was a creative push to create something novel by utilizing a material that had rarely been affected by audio-driven vibrations before. Gallium is special its low melting point of roughly 85 degrees F, allowing it to melt at body temperatures. The setup was to allow the liquid metal to vibrate across a black acrylic plane, swirling in recessed typographic pools that collectively made up the construct of the Thump logo.

To create the organic ripples that affected the Gallium, the team hooked up a series of Synthesizers and cultivated a series of custom built sine-wave frequencies from a large speaker that caused the metal troughs resting on it to ripple and form detailed sound wave patterns. These sounds were then synchronized with the camera's frame-rate, thus achieving the time frozen formation look, and also were used in the final sound design and mix so the visual feedback felt real and authentic.

    Impressive. Most people just stick with the stock sine-wave frequencies.

    This leads to the obvious question: Where does one acquire a quart of gallium?

      Not quite the same effect, but head to your local grocery store and create your own cornstarch lifeform:

      (you could also use e.g. Wood's metal, but that contains lead and cadmium)

      Since no one seems to have answered: amazon.com, like everything else these days. The vendors sell it by the gram, not quart, though.

        That works out to about $600-1000 a quart. Bargain! I also see a defunct seller of gallium teaspoons on Amazon. Pretty elaborate prank.

  3. I'm sure this will show up in a movie in the next year or two. For some reason it reminded me of Fringe.

    --artist bullshit to english translation--

    We fed in 60ish Hz and hoped it'd look cool.

    Gallium's fun stuff. Here's some Science, from Scientists:
