Step 1: Open or start a chat in iMessage
To start we need to get an iMessage chat going so that we can use our effect. Either open an existing chat (go into the messages app, then tap on a conversation), or start a new one (tap on the writing icon at the top right hand corner, then type in the person or people’s names)
Step 2: Type your message
In the text box, type out the message you want to send with the effect.
Step 3: Long press the send button
Long press on the send button rather than tapping and a list of effect will appear.
Step 4: Select your effect
Select your effect (from invisible ink, which reveals when you rub over the message, gentle, loud, and slam) and then tap the send arrow to send the message along with the effect you desire.
To cancel and not use one of these effects, tap the cross.
You can also use full screen effects
If you tap right at the top of the page, you can use full screen effects such as lasers, echo, spotlight, balloons, confetti, “love”, fireworks, shooting star (perfect for “the more you know”) and “celebration”.
