I understand Cherenkov effect only forms in your eye, not projecting in the room like that 🙂
Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium (such as distilled water) at a speed greater than the phase velocity (speed of propagation of a wavefront in a medium) of light in that medium.[3] A classic example of Cherenkov radiation is the characteristic blue glow of an underwater nuclear reactor.
Thanks wiki. So yes, it won't be glowing like that unless Ehsex is underwater. But also you don't need eyes to get the bloo glow
