How do I get the part to move?

How do I get the part to either move to where I click, sit in the center of my Torso or even just stay in my hand? Any help would be great.

tool = script.Parent
part = script.Parent.Part
handle = script.Parent.Handle

function Use()
part.CFrame = CFrame.new(handle.Position)
part.Shape = "Ball"
part.Transparency = 0

wait(0.2)

part.BrickColor = BrickColor.new("Really black")

	for i=1,10 do
		
		wait(0.5)
		part.Anchored=true
		part.Size = part.Size + Vector3.new(5,5,5)
		wait(1)
		part.Size = part.Size - Vector3.new(5,5,5)
	end
	wait(5)
end

tool.Activated:connect(Use)
