Johnny draws a sketch on the chalk wall, the children are in awe and they all come together and put their hands on top of the etching. This causes the wall to implode and open up a hole in the wall. I may add another short moment before the children approach the wall. I may have the drawing begin to animate slightly, then that animation will stop once the children put their hands on it and the wall will collapse and the hole will appear. Every few seconds is a story unto itself and it a long but precious process.
