I tried to shoot a few videos, and they didn't really understand the concept. They kept freezing in place and making the "peace" sign.
In the first video, the kids are playing (and cheating) with flashcards with names of different foods.
In video #2, I was trying to have each kid introduce him/herself, but they got a little shy and forgot what they were supposed to say. The boy running around is Misha, who starred in my blog last year.
