In the last talk-through, you learned how to use the “number scrubber” to quickly try out different numbers. Since you can’t see the way the cursor moves to change the number scrubber in the talk-through, here’s a GIF that shows the motion:

ellipse(leftX, 150, 126, 97);
ellipse(leftX+62, 150, 70, 60);
ellipse(leftX-62, 150, 70, 60);

You click on the number, then click and drag on the arrows that pop up above it. Number scrubbing is great because of how easy it makes experimentation. Try it out in the challenge!
