Have you ever been for a swim with your Apple Watch or maybe spilt your favorite drink on it? If you did, you’d realize that the watch’s speakers sound muffled, and in some cases, the watch will enter a state it calls ‘Water Lock.’
Water Lock is a feature that preserves the watch from water damage. The screen will be unresponsive, and all you can do is turn the crown, which will emit a sound frequency that will push out the water trapped in the speaker slits on the left of the watch.
Some of you might already know about this feature, but from your eyes, it could look like it’s just squirting out small amounts of water. But a lot more goes on beneath the surface.
YouTube channel The Slow Mo Guys made a new video showing you what goes on with this technology and gives a great explanation of what’s happening.
The Slow Mo Guys, as their name implies, create videos using a camera that is capable of shooting in 1,000 frames per second. The footage can then be slowed down to more than 40 times the normal speed to show you what’s happening.
They have done many videos like blowing up objects, slicing soda bottles, and even did a video with Will Smith using a flamethrower.
