The quickest way to fill a glass

Just sink it with a splash down into the water, perhaps into a filled bath tub...?
It will be filled within a tenth of a second.

You have an empty glass in one hand, the faucet knob in the other. The faucet is not turned on.

If someone was timing you, how could you fill the glass the fastest? (assume it would fill without foaming so you can turn it on full blast)

Would you lift the glass up and down? Does it make any difference?

The fastest way to fill it would be to empty it. It does not say what the glass needs to be filled with does it. How about air?

The timer is attached to the tap? That says water to me.

That could be a red herring 😛
