Researchers have developed a 'freeze ray' that relies on thermodynamic quirks to chill its targets.
, and higher—but according to mechanical and aerospace engineer Patrick Hopkins, shooting a focused jet of matter’s fourth state can offer some incredibly interesting thermodynamic results.
In their experiments, Hopkin’s team fired a purple jet of helium-generated plasma through a thin needle coated in ceramic onto a gold-plated target. They then measured the effects on the target’s surface using specialized, custom microscopic instruments, only to record some incredible results.
