Why does it glow blue? It's the Cherenkov radiation:
'Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium.'
It's going faster than the speed of light (in water). The blue glow is basically a sonic boom but for light.
