Blankrupt by Josh Janousky
You borrow a spectator's credit card -- any color or style will work -- and with a wave of your hand, you cause the markings to disappear completely. You are left with a clear credit card that can be immediately inspected by the spectator. Upon command, you change the credit card back to its initial condition and hand it right back.
Blankrupt is a unique "omni" style prop that allows you to turn a borrowed credit card clean. Easy, medium, and difficult methods are taught by creator Josh Janousky, and you are supplied with two durable, clear credit cards that will last a lifetime of performances. Although there are many effects that allow you to make an object clear, a vast majority are objects that you, the performer, must supply: your pen, your cards, your coins. Blankrupt is unique because the object you make clear is a borrowed, precious object: a spectator's credit card.
