Hi if you want to make your message send in Invisible ink, add a fireworks effect to it, balloons and more write out your message. If you have 3d touch press on the send button if you don't have 3d touch double tap and hold on the send button to bring up the menu. Voice over reads expressive messages that are sent as well as sometimes playing the sound. Double tap on Invisible messages to reveal the message. Tap back are reactions to comments such as hearting a message. To respond to a message swipe down on a message and double tap on react. This is really cool and neat!
