Moving objects in script?

I have tried this in every way I could think of and in WILL NOT move the object (btw, I don't need the model to be there, that was just another failed attempt)

while wait (5) do
	Model = Instance.new("Model", workspace)
	Ball = Instance.new("Part", Model)
	Ball.Shape = "Ball"
	Ball.BrickColor = BrickColor.new("Really black")
	pos = Vector3.new(script.Parent.Parent.Torso.Position - Vector3.new(0,10,0))
	Model:MoveTo(pos)
	Ball.Touched:connect(function(hit)
	local Boom = Instance.new("Explosion", Ball)
	Boom.Position = Vector3.new(Ball.Position)
	Boom.BlastRadius = 10
	Boom.BlastPressure = 10
	end)
end
