Some of the funnest new features coming to iPhone and iPad are the bubble effects in iMessage for iOS 10. With them, you can SLAM down a message or send it softly. You can light the screen with lasers or fill it up with balloons. But what do you do when you try to use it and nothing happens?

The easiest fix is to check your accessibility settings, namely: reduce motion. Bubble effects rely on the very physics engine reduce motion disables. So, if you turn on reduce motion, you turn off bubble effects. It's not obvious, but it's what happens.

Note: If you turned on reduce motion because iOS animations cause vertigo or similar reactions, leave it off. You're not missing any real functionality with bubble effects, only fun. If you turned on reduce motion because you think the lack of animation makes iOS faster, feel free to turn it back off. iOS with reduce motion on is actually a fraction of a second slower — it's just a trick of perception that makes it seem faster.
