TT - It is filtered out by TM which I only just learnt

. Produce silks, vanish silks, vanish cigarettes, switch bills, swallow a borrowed necklace and pull it out of your stomach

(no... really)
It is a great gimmick and it will last you for ages and believe what everybody is saying (including me) ... they will not see it!
I never knew how Crazy Mans Handcuffs worked up untill a little while ago and I get amazing reactions. A true classic but one that no one knows! Nice slow penetration of two elastic bands, one can be held by the spectator. Can be bought very cheaply as well, so that is my recommendation.
