2. Make the secret a lot more trouble than the trick seems worth. You will be fooled by a trick if it involves more time, money, and practice than you (or any other sane onlooker) would be willing to invest. My partner, Penn, and I once produced 500 live cockroaches from a top hat on the desk of talk show host David Letterman. To prepare this took weeks. We hired an entomologist who provided slow-moving, camera-friendly cockroaches (the kind from under your stove don’t hang around for close-ups) and taught us to pick the bugs up without screaming like preadolescent girls. Then we built a secret compartment and worked out a devious routine for sneaking the compartment into the hat. More trouble than the trick was worth? To you, probably. But not to magicians.
Unlike card tricks done on the streets or on stage and card cheating, cardistry is solely about impressing without illusions, deceit, misdirection and other elements commonly used in card tricks and card cheating.[10] Cardistry is the art of card flourishing, and is intended to be visually impressive and to give the appearance of being difficult to perform.[10] Card flourishing is often associated with card tricks, but many sleight of hand artists perform flourishing without considering themselves magicians or having any real interest in card tricks.[10]
Spin a straw around the top of a bottle using only your mind. While no one is watching, take a paper-wrapped straw and rub your hand up and down its length a few times to generate static electricity. Be careful not to tear the thin paper wrapper. When you're ready to do the trick, lay the straw across the top of a bottle or another container with a narrow opening, with its center point directly over the mouth. Raise your hands over the ends of the straw and wave them forward and backward in a mystical manner. The static charge will cause it to rotate without you ever actually touching it.
Smash a cup through a table “accidentally.” Explain to your audience that you're going to pass a magical ball through a solid tabletop using a small cup and a “cloak of concealment” (an ordinary piece of paper). Place the cup upside down over the ball, then mold the paper around the cup so that it covers it completely. Pick up the paper-covered cup to give your audience one last look at the ball. As you do, drop the cup into your lap inconspicuously and cradle it between your thighs. Put the cup-shaped paper shell back over the ball and give it a smack. Remove the cloak to show that the ball is still there, but the cup has rematerialized beneath the table.[8]

Bend and re-straighten any spoon instantly. Hold the spoon upside down with the head pressed against a table or similar surface and act like you're gripping the handle firmly in both fists. Instead of actually wrapping your hands around the spoon, loop the pinky finger of your bottom hand around the point on handle directly above the head and keep the rest of your fingers poised just in front of the handle, along with your entire top hand. Push both fists down towards the tabletop as though you're bending the spoon by force while slowly lowering the handle to a horizontal angle. Finish the trick by quickly reversing the motion and magically restoring the spoon to its original shape.[2]
