The child hates to clean his room so he gets out his book of magic spells and use one to clean the room. Unfortunately, the room gets worse with clothes etc. This happens again twice. The child decides he might as well clean up this mess and proceeds to do so. When the room is finally clean, the child is ready to throw the magic book in the garbage.
More stuff flies in.
A person enters the room pulling a rope behind him. The person can top the stunt later in the meeting by coming in while pushing a rope which has been made stiff by tying it to a wire. An object flies through the air and lands on the stage. Boys come onto stage and begin examining the object. An expert with a magnifying glass strides onto the stage.
