What was the woman holding in her hand in the "1928 time traveler" video?

I had trouble finding the original video, here’s the yahoo search results: http://video.search.yahoo.com/search/video?p=1928+time+traveler
and if you want a good laugh here’s a fox news analysis: http://www.youtube.com/watch?v=gAhavO89LqQ

I feel like there’s a very small percentage of people who actually believe this is evidence of time travel, but I wonder what the woman is actually doing. Her mouth is moving, so I think she’s talking into a potato or something.
