Student will then click the 1st link on the sidebar. They will call this video "2", and write it on a piece of paper. They will then click the 1st link on the sidebar of this video. This third video will be "3". Students will continue this process for 25-50 videos.

When students are finished, we will discuss whether their video sequence fell into a looping pattern, or whether all the videos of their sequence were different. I would compare a video sequence that "loops" to a rational number - all rational numbers have a pattern of decimal digits that eventually repeats itself. I would then compare a sequence that never repeated itself to an irrational number, which never contains a repeating pattern of digits.

I would then tell students that it is impossible for a video sequence on youtube to be "irrational", because there is a finite number of videos on youtube, so eventually any sequence

*must*fall into a loop.

What do you think?
