Here's the effect: Let the child reach into a colorful cloth bag to prove that it is empty. Drop a silk handkerchief into the bag and ask the child is to wave a wand above the bag to make the handkerchief vanish. (You can have the child make several funny attempts before he is successful). Finally, the handkerchief really vanishes and in its place is a Clown's Hat. Place the hat on the child's head, then turn the bag inside out. The bag becomes a Clown's Coat that the child can put on to become an Official Magic Clown!
