Here’s a quick tip to safely show a YouTube video without the worry of advertisements.
Type a dash between the t and u in the word “tube” in the URL and the video will enter full screen and eliminate ads.
For example, instead of sharing this link: https://www.youtube.com/watch?v=zerUb9zU1L0 – share this link: https://www.yout-ube.com/watch?v=zerUb9zU1L0
