Classic effects with flap cards

TL;DR: The classic flap card effects are a visible change of one card into another, two cards that swap places in your hands, a torn corner that flies back into place, multi-phase changes, and a back that changes colour. Most were already in print by 1897. What separates a good flap card routine from a gadget demo is the reason for the change and what you do with the card afterwards.

Why learn the classic flap card effects?

A flap card on its own does one thing: it changes. The effects are what turn that change into a story. Knowing the classics gives you a menu of proven plots, and it stops you from treating every new flap gimmick as if it were a brand-new idea.

If you’re new to the gaff itself, start with our guide to flap card mechanics and theory. This post is about what you can do with one.

What counts as a flap card effect?

An effect is what the audience sees and remembers. The method is how it happens. Many very different effects share the same flap method, so it helps to group them by what the audience sees:

• Change: a card becomes a different card.
• Transposition: two cards swap places.
• Restoration: a damaged card becomes whole.
• Multi-phase change: a card changes several times, or changes size.
• Colour change: the back or the colour of a card changes.

How do flap card effects fool an audience?

Every effect here relies on the same idea: the audience sees what looks like one ordinary card, and the change happens in a moment they can’t rewind. The routines in old books add two things around that moment.

First, a way in. In Roterberg’s torn corner trick, for example, the chosen card is switched for the prepared one using a sleight called the bottom change before anything magical happens. Second, a way out, so the audience is left with something that looks normal. The better routines plan both.

When do you use each classic effect?

These are the main plots, with where you can read the original descriptions. All of them appear in August Roterberg’s New Era Card Tricks (1897).

Effect	What the audience sees	Best for
The flap card	A court card is shown, the performer breathes on it, and it visibly changes into a different card.	A quick, clean moment of magic
Double change	One card in each hand; a quick motion and the two cards have swapped places.	A short, visual opener
Torn corner card	A corner is torn off the chosen card, thrown at it, and the card is instantly restored.	Parlour shows, a few feet away
Quadruple changing card	A card is rubbed and changes, then changes again, several times in a row.	A running gag in a longer routine
Changing and diminishing card	A card changes, shrinks to half size, then vanishes completely.	An ending that leaves nothing behind
Nonpareil card	A card changes, then the new card is handed out to be examined.	When the audience is close

The modern favourite is the colour change. A red-backed card or deck seems to turn blue, or the reverse, often as the finish of a colour-changing deck routine. This is where today’s commercially made flap cards are usually aimed.

How should you learn these effects?

Work through them in order of difficulty, not order of impact:

1. The plain visible change. One card, one change, no switches. This teaches you how to hold and release the gaff.
2. The colour change. Same handling, but now the card has to match the deck around it.
3. The restoration or transposition. These need a clean switch in or out, so learn a basic switch first.
4. Multi-phase changes. The more changes, the more chances to flash something. Save these until the single change is automatic.

Whatever you choose, give the change a reason. A wrong card that corrects itself, a card that “heals”, or a deck that matches a spectator’s choice all play better than a change for its own sake.

Which products help with flap card effects?

• Forever Flap by Nicholas Lawrence: a blue to red and a red to blue flap gimmick with a 23 minute video, designed as a companion to a colour-changing deck routine. The description says you can go straight into deck examination after the change.
• Blind Flap by PH and Mario Tarasini: a download for a visual colour change of a card with a coin resting on top, the same coin before and after. Read our Blind Flap review first.
• New Era Card Tricks by A. Roterberg: a free ebook with every classic in the table above.

What are the common mistakes with flap card effects?

• Changing it too often. One clean change hits harder than four rushed ones, unless the repeats are the joke.
• No reason for the change. Without a story, the audience studies the card instead of enjoying the moment.
• No way out. If the routine ends with the gaff in your hand and someone reaches for it, plan the ending before you perform.
• Mismatched cards. A flap card with a different back design or a faded colour stands out next to your deck.
• Performing at the wrong distance. Roterberg himself suggested the torn corner card for the parlour, and an improved version for audiences further away.

Frequently asked questions

What tricks can you do with a flap card?

The classics are a visible change of one card into another, two cards swapping places, a torn corner being restored, a card changing several times, and a card back changing colour.

Do flap card tricks need sleight of hand?

The basic visible change needs only careful handling. Restorations, transpositions and routines that end with a normal card usually need a simple switch as well.

What is the best first flap card effect to learn?

Start with a single visible change of one card into another. It teaches the grip and release that every other flap card effect depends on.
