I came across a video titled Hummingbirds drink from red Solo cup in hand, which has over one hundred thousand views, and presumably has been viewed in places other than YouTube.
The hummingbirds look very small compared to the "hand" in the video. According to Wikipedia, the smallest hummingbird is 5 cm long at adulthood. Also, the "hand" moves up and down, but the "fingers" don't move at all relative to the hand.
Is the hand fake, as opposed to a real human hand?
