removing multiple objects

[durf]

Hello,

I cannot figure out how to remove or delete multiple objects that have been created this way:

	def balls():
		ball = ballOriginal.copy()
		ball.scale(.5,.5,.5)
		ball.collideSphere()
		ball.setPosition([0,20,0])
	vizact.ontimer2(0,200,balls)

How can I remove all 200 of those balls?

Thanks
