The block sets the Pen Size to the given number. The pen draws a trail of circles. The diameter of the circle, in pixels, is equal to the pen size.
In this example, we will analyze the effect of the bounce property of the sprite using a ball. We will track the ball using the pen extension and the color will change with the y velocity of the ball.

The coefficient of restitution is the ratio of the final to the initial relative speed between two objects after they collide. In PictoBlox it is controlled with bounce property. It varies from 0 to 100%.
The following is the code we will use:
Let’s see how the code work will various bounce values:
- Bounce = 10
- Bounce = 60
- Bounce = 70
- Bounce = 80
- Bounce = 90
- Bounce = 99
Earth vs Moon
If we change the gravity with a bounce value equal to 90, we can simulate how the ball will work on the moon.
