Your iPhone's Messages app isn't just for sending texts. You can also send photos, videos, and a wide variety of special effects.

While you can pick and choose from some of these effects by holding your finger down on the send button, other effects only activate when you send certain words or phrases.

Apple doesn't advertise these effects - they're hidden "Easter Eggs" on your iPhone instead.

A full guide to iMessage effects

Here's a guide to the words and phrases that will cause effects in the Messages app, and hopefully delight both you and your recipient.

"Happy New Year"

Colorful fireworks fill up your screen when you send New Years' wishes.

When you send a "Happy New Year" message, your text will be accompanied by its own fireworks show.

"Happy Chinese New Year"

You can experience a miniature Chinese New Year celebration with this effect.

This effect is particularly cool, and comes packaged with its own firecracker-esque vibration pattern when you send it.

"Happy Birthday"

When a birthday phone call isn't possible, why not send balloons with your text?

Text "Happy Birthday" to summon a flood of colorful balloons. Shortened versions, like "HBD," won't trigger the effect.

"Congrats" or "Congratulations"

The fun of confetti, minus the headache of cleaning it up afterward.

When you congratulate someone, confetti will rain down from the top of your screen. You can also try sending congratulations in different languages, such as the Spanish "Felicitaciones" or Indonesian "Selamat" — these often work as well.
