This problem appears in the movie Die Hard 3.  Bruce Willis and Samuel L Jackson had 30 seconds to solve it in order to prevent an explosion which would have killed them!

Luckily, the penalty for getting problems wrong here is not so severe!

Fill the 5 cup container full....pour 3 cups into the 3 cup container....throw these 3 cups out.........there will be 2 cups now in the 5 cup container....pour these 2 cups into the 3 cup container.....

Fill the 5 cup container full, again......pour 1 cup into the 3 cup container which is now full.......the 5 cup container will now contain exactly 4 cups.....!!!!
