Sock stuck in vacuum cleaner?

I'm sure I'm not the only one who has been surprised by a sock.

At one moment it was on the floor and the next moment it was sucked up by the vacuum cleaner and the result was that no air came out or in the hose.

Take a handful of marbles, go somewhere safe, like in the garden en shake the marbles in the hose right on top of the sock.

It'll come out.

The marbles too, so when you shake above a bucket you'll have them back the easiest way.
