This is my first test to make working marble simulations in scratch. this test has one marble that will bounce around the screen randomly. The marble's size can be changed by using the slider at the top left. All variables are shown to allow you to see how this works. (mostly) The marble will be slowed down when it hits a wall (the edge). there is also an arrow to show the marble's direction. The marble will also start in a random position and direction each time you use it.
