The CTW document is a 20 page manuscript describing in very fine detail how to construct the clever gimmicks which will allow you to perform the classic Card through Window effect using 'desktop technology' (scissors， tape， glue， etc.) and materials included with this booklet.

Each step of the process is very easy to follow thanks to clear and concise text， assembly diagrams and cutting templates， making the construction of the gimmicks simple and straight forward.

Effect 1：

A spectator selects a card from a deck. A corner is torn from the card and given to the spectator as a receipt. The magician claims he will make the card completely disappear and， after some by-play does exactly that!"Do you know where it went "he asks. The spectators confess that they do not."Look over there， do you see what's taped to that window "The spectator turns around to find their selection taped firmly to a nearby window， the corner receipt matches perfectly!"That's pretty weird how I made your card appear there isn't it "The spectator agrees."I'll show you what's even weirder though."The magician passes a fan of cards over the selection and it very visually jumps right through the window! The tape is removed and the spectator can remove the card from the other side of the glass! The corner still matches perfectly!

Effect 2：

A spectator selects a card from a deck. A corner is torn from the card and given to the spectator as a receipt. The card is placed face up into the middle of the deck， the deck is bound with a rubber band and the spectator holds it between her palms. The magician leads the spectator to a nearby window where a small 'curtain' bearing a large question mark is seen.

He explains that earlier on in the day he taped a playing card on to the window as a prediction， the tape is seen to be protruding from either side of the curtain. After a suitable build up the magician lifts the curtain and a card matching the spectator's selection is seen to be taped firmly to the window. The magician points out that his prediction card also has a corner missing and asks the spectator to go through the deck and find his face up selection. The spectator finds that his selection is gone! The corner receipt is compared to the card on the window and they are seen to be a perfect match! Here comes the best part：

The magician passes a fan of cards over the selection and it very visually jumps right through the window! The curtain is removed and the spectator can remove the tape and the card， which really is on the other side of the glass， and everything is examinable. The corner still matches!
