ELI5: Why does water go gluglugglug when we pour it too fast? Will it take a shorter time to empty the container if we pour a bit slower?

Because air has to fill the empty space the water leaves behind it. If you have a container with another hole large enough to suck air in behind the water (while the contain is pouring), it'll pour faster and not have the mentioned issue.  

Alternatively if you can spin the container for form a vortex as the water pours out, it'll also pour faster because air can go through the middle of the vortex instead of the water having to temporarily stop so air can flow through.
