Duct Tape Cork

If you open a bottle of wine and you don't drink the hole of it, than you'd better cover it back.
But what if the cork doesn't fit back? Use some duct tape!

Nowadays the corks are not made out of cork any more. They are made of plastic. And a plastic cork can't be put back in the bottle neck.

Put a small piece of duct tape on the bottle neck.

Cover the neck around with duct tape; make it in the form of a tube.

With two fingers flatten the duct tape tape tube so it is sealed.
