Look at those kids! Interest starts fading the second the explanation starts.
Why is that? Well they anticipated an explanation that was as cool as the effect they have seen. It was not. In fact it was disappointing. As this could be the main reason not to expose magic. Never show them how the sausage is made.
I could be wrong. It probably was a long day for the kids. This is not the only video that Jason Suran did. The kids appear in a few of them.
So are those the kids the target audience for the video? If so, heaven help us.
