Since the release of the iPhone 6 and 6 Plus, I'm sure many people have been once again experimenting (read: arsing around) with the slow-mo video function, which is now twice as fast (240fps vs 120fps on the iPhone 5s). However, many people will have no-doubt noticed that if you upload the video to Facebook using the iOS app, it doesn't retain its "slow motion" properties - it merely plays back at normal speed once uploaded to Facebook. The solution? It's really rather simple. Share it using the iOS Facebook (or YouTube) integration, by using the sharing/send feature whilst viewing the video in the Photos / Camera Roll app (the button that looks like a little square with the up arrow). Uploading it this way will ensure that when someone views it on Facebook, it'll play nice and sloooowwwwlllyyyyyy.
