Did you know that you can send a disappearing photo, video, or Boomerang to another account using Instagram Direct Messaging? Me neither, but this is how you do it:

• Create an Instagram Story as you would normally do, but don't post it
• Tap the Arrow icon at the bottom right of your screen, it looks like this: >
• Choose who to send the story to
• Tap Send
• Sending a message this way will make the photo or video disappear after someone sees it
