# A Week of Pi, Day 4: Videos to Celebrate Pi Day

Earlier this week, we explored what pi is, discovered some Pi Day contests, and learned about some Pi Day activities.

Now for some real fun; videos that make pi even cooler than it already is:

- The Pi Song is simple, but catchy.

- e + pi is goofy (and thus, I love it).

- Pi Rap is educational and fun.

- Pi Day Domino Spiral is a time lapse video of someone building a huge spiral out of dominoes. Pretty cool.

Come back tomorrow on 3.14 for our final Pi Day post.
