You know, that does fit the video. Your statement made me think of the chimps.....notice they were behind bars the whole time?That is because their first action would have been to destroy the box and get the treat.The chimps only resort to a "logical" approach when the direct approach is impossible.The kids, on the other hand, were allowed close contact with the box because their "conditioning" would prevent them from taking that direct approach and trashing the box, the same way it would not allow them to cut the ceremony and go right for the payoff.And you are right....the kids would probably bash the box if they were left alone and told there was candy in it.
