Actually, watching them again multiple times, a bit of the magic was lost. Especially on the second one where the boys are playing ball. It looks as if they might be pulling a string to make the little gnome jump up. I also wonder if they stopped the film so abruptly there because they began to laugh. Because as I perused similar videos linked to it, I could tell it has become a popular joke to make these type of videos. Muddies the water.
