When you have a blocked nostril, what happens when you hold both nostrils and blow hard that causes them to unblock for a brief second?

In: Biology

You pressurise your nostril cavity causing it to expand under the pressure giving the feeling of being unblocked untill you release the pressure. If you need a visual example then put a marble into the neck of a balloon that is larger than the neck, you will have to stretch it to fit, then blow the balloon up and the marble will roll into the balloon as the neck expands under the pressure.
