Ever been on a FaceTime call and suddenly, out of nowhere, a swarm of balloons floats across your screen? It’s kinda startling the first time it happens. You probably just waved or made a peace sign without thinking, and Apple's software decided it was time to party.
Honestly, these 3D augmented reality effects—officially called Reactions—are one of those "hidden" features that people either love or accidentally trigger during a serious work meeting. If you’re using an iPhone 12 or later (or a Mac with Apple Silicon), your camera is basically watching for specific hand signals to turn your video feed into a miniature movie set.
It’s not just about being "extra." These reactions work in third-party apps too, like Zoom and Google Meet, which can lead to some pretty hilarious (or awkward) situations if you don't know the full list of what triggers them.
The Complete List of FaceTime Reactions
There are currently eight specific gestures that trigger these 3D effects. Most people only know the thumbs-up one, but there’s a lot more depth to the system.
1. The Classic Thumbs Up
This is the easiest one. Just hold up a single thumb. A little 3D speech bubble with a thumbs-up emoji pops up next to your head. It’s perfect for when you’re on mute but want to show you’re following along.
2. The Thumbs Down
Same vibe, just inverted. One thumb down gives you the "dislike" bubble. Use this sparingly if you don’t want to be a vibe-killer.
3. Heart Emoji
Put your hands together to form a heart shape (the "hand heart"). When the camera recognizes it, a flurry of red 2D and 3D hearts will erupt from the center of your hands. It’s a favorite for calls with family or that "just started dating" phase.

4. Fireworks for Big News
This is where things get flashy. If you hold up two thumbs up at the same time, the background of your video dims, and colorful fireworks explode behind you. It’s surprisingly loud (visually speaking), so maybe don't do this while someone is giving a presentation.
5. Rain (The Sad Mood)
If things aren't going great, hold two thumbs down. The screen will actually darken, and digital rain will start pouring down on your head. It’s incredibly dramatic.
6. Balloons
Raise a single peace sign (victory sign) with one hand. Multi-colored balloons will float up from the bottom of the frame.
7. Confetti
Throw up two peace signs (one with each hand) and you’ll get a rain of confetti. It’s basically the "Happy Birthday" or "I got the job" button.
8. Laser Burst
This one is for the rockers. Make the "sign of the horns" (🤘) with both hands. This triggers a rhythmic, colorful laser show that scans behind you. It’s definitely the most intense reaction in the toolkit.
Why Aren't My Reactions Working?
It’s frustrating when you’re trying to celebrate and nothing happens. Usually, it's one of three things. First, check your hardware. You need an iPhone 12 or newer. If you’re rocking an iPhone 11 or an older SE, the processor just isn't beefy enough to handle the real-time depth mapping required for these 3D overlays.
Lighting is the second biggest culprit. If you’re in a dark room or have a bright window behind you, the camera struggles to "see" the silhouette of your fingers.

How to Manually Turn Them On or Off
Sometimes Apple updates will toggle this off by default, or you might want to kill the feature so you don't accidentally send lasers during a job interview.
- Open the Control Center during an active FaceTime call (swipe down from the top-right corner).
- Tap the Video Effects button (it usually says "FaceTime" or "Effects").
- Look for the Reactions icon. If it’s highlighted, gestures are on. Tap it to disable them.
Beyond Gestures: The Manual Menu
You don’t have to be a mime to use these. If you're on a Mac or just don't want to wave your hands around, you can trigger them with a click. On a Mac running macOS Sonoma or later, there’s a green FaceTime icon in the menu bar. Click it, then click the arrow next to Reactions. You can trigger all eight effects manually from there.
On an iPhone, you can long-press your own video tile during a call to bring up the reaction menu. This is way more reliable if you’re in a low-light environment where gestures are failing.
Pro Tips for Better Reactions
If you want the effects to look "clean" and not glitchy, keep your hands away from your face. The AI needs to see the clear outline of your hand against the background. If your hand overlaps with your chin or hair, the sensor gets confused and won't trigger the animation.
Also, hold the gesture for a full second. It’s not an instant "flash" trigger; the system needs a beat to confirm you aren't just adjusting your glasses or itching your ear.
Actionable Next Steps
- Test your setup: Start a FaceTime call with yourself (using another device) or a close friend to see how the lighting in your usual "calling spot" affects the sensors.
- Check your settings: If you're heading into a professional meeting on Zoom or Teams using your Mac/iPhone, remember to toggle "Reactions" off in the Control Center beforehand.
- Update your OS: Ensure you're on at least iOS 17 or macOS Sonoma, as these were the foundational updates that introduced the expanded gesture library.
