This is a video of musician Astaremi showing off the custom liquid-filled electric guitar he built, using two colored liquids of differing viscosities so they flow around each other in there kind of like a lava lamp. Apparently the build was inspired by Kirk Hammett’s Wavecaster and John 5’s lava lamp guitar, both of which are basically the same thing (the lava lamp guitar just has a blacklight reactive liquid inside). That’s cool. But cool enough to wow the audience and distract them from noticing I have zero musical talent? I’ve never had so many beer bottles thrown at me!
