Chris Wojtowich’s CD3PO

Make a CD or flat disc appear to completely vanish from your hand using a simple drop, fast movement and the camera itself. There are no editing tricks required.

DIFFICULTY: Beginner / Intermediate
PROPS: CD or Flat Disc & Camera
PRACTICE: Around 20-30 Minutes

THE EFFECT

You hold a CD or flat disc openly in your hand.

With one quick swing of your arm, the disc seems to instantly disappear.

There is no video cut, transition or editing trick. The vanish happens during the actual recording.

The secret is surprisingly simple. You drop the disc at exactly the right moment and move your hand away quickly enough that the camera does much of the work for you.

WHAT YOU WILL NEED

• One CD or Flat Disc
  
• A Phone or Camera
  
• A Table or Soft Landing Area
  
• A Little Practice With Timing
  

Important: This effect is designed primarily for a camera. Your positioning, timing and camera settings all affect how convincing the vanish looks.

THE METHOD

The basic idea could hardly be simpler.

You drop the disc and move your hand away.

The secret is doing both actions at almost the same moment.

Because the disc is thin and moving quickly, individual video frames may fail to show it clearly as it falls. Motion blur, timing and the camera's frame rate help hide the falling disc.

Around 24 FPS is a good place to start, although the vanish can also work at higher frame rates depending on your speed, lighting and camera.

STEP 1 - POSITION THE CAMERA

Place your phone or camera in front of you and frame the shot so your hand and upper body are clearly visible.

Keep the area directly underneath your hand outside the most important part of the frame if possible.

You want the audience watching your hand, not looking for where the disc could go.

Tip: Start by recording at around 24 FPS. Once you understand the timing, experiment with other frame rates.

STEP 2 - CUP THE DISC IN YOUR HAND

Hold the disc naturally in one hand.

Slightly cup your fingers around it so you have control of the disc but can release it instantly.

Do not grip it tightly.

Your fingers should be relaxed enough that the disc can simply fall when you open your hand.

Important: The release needs to happen without any obvious throwing motion.

STEP 3 - PREPARE THE ARM SWING

Begin moving your arm as though you are going to quickly sweep your hand outward.

The movement should be confident and natural.

Do not make the motion unnecessarily huge. You only need enough movement to pull the viewer's attention toward your hand.

Tip: Think of the arm movement as the magic gesture. The audience should follow your hand instead of watching underneath it.

STEP 4 - DROP THE DISC

This is the entire secret.

Just before your arm swings outward, release the disc.

Allow it to fall straight down.

Do not throw it backward or try to flick it away. Simply let gravity take over.

The release happens a fraction of a second before the larger movement of your hand.

Critical Moment: Drop first, then immediately move the hand. The two actions should appear to happen as one continuous motion.

STEP 5 - MOVE YOUR HAND OUT FAST

The instant the disc leaves your fingers, quickly sweep your empty hand outward.

Your hand continues moving as though the disc were still travelling with it.

On camera, the viewer's eyes follow the hand.

Meanwhile, the thin disc is already falling.

When the timing is right, the camera may capture very little usable detail of the falling disc, making it appear to simply disappear.

That's it! Drop the disc, move the hand and let the camera help sell the illusion.

WHY THE ILLUSION WORKS

A video camera does not record every instant continuously. It captures a series of individual frames.

At around 24 frames per second, there is a small amount of time between each captured frame.

The disc is thin, falls quickly and may also become blurred while moving. If your timing is good, there may be very little clear visual information showing the disc travelling downward.

At the same time, your hand makes a much larger movement that attracts the viewer's attention.

The viewer follows the hand while the disc falls through an area the camera barely shows clearly.

No cuts are necessary. No transition is necessary. The vanish happens during one continuous recording.

CAMERA SETTINGS

Start with your camera at around 24 FPS.

That tends to make the effect easier because there are fewer individual frames capturing the falling disc.

However, 24 FPS is not an absolute requirement.

The effect can still work at higher frame rates if your release and hand movement are fast enough.

• 24 FPS: Good starting point and usually forgiving.
  
• 30 FPS: Can still work with good timing.
  
• Higher FPS: Usually requires faster, cleaner movement because the camera records more stages of the fall.
  

Tip: Record several attempts and watch them back normally and frame by frame. Small timing changes can make a huge difference.

PERFORMANCE TIPS

• Drop before you swing. The disc should already be leaving your fingers as the larger hand movement begins.
  
• Let gravity do the work. Do not visibly throw the disc.
  
• Move the hand quickly. The hand movement gives the viewer something obvious to follow.
  
• Keep the disc flat. A flat falling disc presents less visual information than one wildly spinning toward the camera.
  
• Experiment with your angle. Slight changes in camera height can dramatically improve the vanish.
  
• Watch your recordings back. Camera magic is easier to practise when you can immediately see what the viewer sees.
  
• Use a soft landing area. Dropping CDs repeatedly onto a hard floor can damage them or make unnecessary noise.
  

COMMON MISTAKES

• Moving before releasing the disc. This can cause the camera to clearly see the disc leave your hand.
  
• Dropping too late. The disc may remain visible next to your moving hand.
  
• Throwing instead of dropping. A sideways movement is much easier for the camera to capture.
  
• Moving your hand too slowly. The vanish loses its sudden visual quality.
  
• Using the wrong camera angle. If too much of the falling path is visible, the secret becomes obvious.
  
• Expecting the first attempt to work. The method is simple, but the timing takes practice.
  

PRACTICE EXERCISE

Set your camera to around 24 FPS and record ten attempts in a row.

For the first few attempts, concentrate only on releasing the disc before moving your arm.

Then gradually shorten the delay between the drop and the hand movement until they visually blend together.

Watch the recordings back and look for the point where you can no longer clearly see the disc falling during normal playback.

Once you find that timing, repeat it until the movement becomes automatic.

MAGIC TIP

Do not overcomplicate this one. Cup the disc naturally, release it just before the arm swings, move your empty hand out quickly and let the camera help create the vanish.

The method may only take a few seconds to understand, but getting the timing clean is what makes it look impossible.
