These are two unique and practical effects I perform on a daily basis.
Biteme - A TNR plot using nothing but your mouth and a card. 2 different methods are introduced and the card can be signed.
Dcharger- Take your iPhone(or iPod Touch/iPad), and show the spectator that your battery is completely dead! Oh no! But you are a magician; you can fix these problems... You then ask for the spectators hand. The participant then holds the iPhone with their finger tips and is instructed to let their natural human energy to flow into the the phone. Just a little shake from the spectator charges the phone 100%! (You can now go stalk your ex-girlfriend or go play Sonic 2 ![Ex-girlfriend and Sonic 2 not included])
Watch , listen and learn in over 20 minutes of instruction. Of course in powerful 'hipster' HD.
