I'm sure YOU could make a YouTube video of your hamsters, but I don't think hamsters can make YouTube videos by themselves.

Facebook or youtube
First of all, make sure you upload your YouTube video to Facebook. There are two ways to do this. First, you can embed the video from YouTube. Second, you can upload the video from Facebook. If you want specific details on how to do this, you can go ahead and check Facebook help center.
First, you have to use a little imagination with your YouTube video. Make a video of something a lot of people are struggling on (Example: a hard part of a video game no one knows complete). Second, you can make a video of humor and use a lot of imagination or an impossible subject (Example: Make a paper animation successfully).
