   I was trying to have the circles bounce back down from the top, but I couldn't grasp how 
   to do that from the class notes.

Hi Greta. You're very very close to figuring this out, so I'm going to point you to this section of the Week 4 class notes. I recommend that you carefully read through these two bits of pseudocode, the code snippet that comes next, and the accompanying explanation.

In that example, I was talking about horizontal movement, so I was using the words "left" and "right". But you are talking about vertical movement, so wherever I say "right", you could think about the bottom of the draw window, and wherever I say "left", you could think about the top of the draw window.

Try reading through that, pay attention to the code in blue, and see if you can make a similar addition to your code.

Great work so far!
