Upon Evangelion activation, an electrical current is run through the LCL and it undergoes a phase shift, after which its density, opacity and viscosity appears to approach that of air. However, the LCL remains in a liquid phase and does not undergo a transition: the pilots appear to be surrounded by air, however occasionally air bubbles will float away from their mouths, revealing that they are still in a liquid medium. An amber-colored fluid, visually identical to LCL, escapes from Leliel's body (the ultra-flat "shadow") when the bullets of Unit-01's handgun strike in Episode 16.
