TWO effects that involve a change that happens in your MOUTH!
#1 Bite: An ink change on the back of a playing card. It is placed in your mouth, and your hands don't need to go anywhere near it, yet at your command the ink visibly CHANGES! Also taught are many variations so the card can be given away as a cool souvenir.
#2 Teeth: A whole card changing routine. A playing card is selected and signed by the spectator. It is then folded into courters and held by your teeth in your mouth. With a quick wave of your hand it changes into a completely different colour to what it was before. The card is then unfolded, and the whole card has completely CHANGED! The card can then be instantly handed out for examination.
