COLOR CHANGING MAGIC WAND--BLACK TO GREEN
You hold a black color wand in your hand and try to do some magic. The magic doesn't happen since you need a green color wand to do it. So you pass your hand over the wand and presto, it changes into a GREEN color wand! Since you don't want the wand to do magic on its own ...You pass your hand over it one more time and it changes back into a black wand! Even spin the wand to show that it is absolutely normal! This can be repeated any number of times! Very visual and very easy to do.
