One common way to watch multiple youtube videos at once is by opening several youtube windows (not tab) of a web browser and rearrange them side by side across the screen without covering each other.
But what if we just want every video to be in just one place and not having 10 web browser windows opened at the same time which might consume too much CPU power or RAM.
A website called Youtube Multiplier is capable of performing this task. Playing up to 8 youtube videos in just one tab. Simply copy the URLs of the videos and paste them in the box provided, choose a layout, give the mashup a title, and lastly write the code provided before viewing. You can also then share the mashup for others to enjoy.
