Timelapses.

A timelapse is a faster video of a video. It's good for loads of things, including making a video of a plant or clouds. It shows how something moves in less than an hour, or just less than it took to make a video.

There are timelapse apps where you can make your own. I usually make timelapses of clouds.

A reason why you might want to make a timelapse is that you can see how clouds move, or how a plant moves, since you probably can't see them fast without a timelapse.
