This is somthing that your sectators will have to love you for. Imagine taking a "normal" Bic pen from your jacket pocket and handing it out for inspection(not amazing I know). You then take it back and STAB the pen through you arm. The spectators see the pen go into the arm theres no doubt about that. Blood starts pouring from your arm(optional)as you retract the pen. Then pen and your arm can straight away be examined by the spectators.
You will love this effect. I?ve only used it once but stopped because it didnt fit in with my routine, but it may fit in with yours. Or its a good way to get noticed when table hopping, I mean whos going to forget a guy strolling up to their table and stabing a pen thru his arm? As I have mentioned blood is optional so give it a go both ways(with and without blood) because even without the goreyness(is that even a word?)it is still very visual and a great reputation maker.
