While loop glitching the debounce?

I try to use for everytime, but I want to learn to use the while loop.Everytime I try t, it glitches the debounce.Any help?

function pizza(mouse)
	if debounce == false then
		debounce = true
		local x = Instance.new("Part")
		x.Shape = "Ball"
		x.CanCollide = false
		x.TopSurface = "Smooth"
		x.BottomSurface = "Smooth"
		x.Transparency = 0.7
		x.Parent = Workspace
		x.Size = Vector3.new(10, 10, 10)
		x.Name = Player.Name
		x.BrickColor = BrickColor.new("Black")
		game.Debris:AddItem(x, 10)
		y = Instance.new("BodyVelocity")
		y.maxForce = Vector3.new(math.huge, math.huge, math.huge)
		y.velocity = Player.Character.Torso.CFrame.lookVector*160
		x.Parent = Workspace
		y.Parent = x
		f = Instance.new("Fire", x)
		f.Heat = 0
		f.Size = 30
		x.CFrame = Player.Character.Torso.CFrame*CFrame.new(0, 0, -10)
		while x do
			wait(0.1)
			x.Size = x.Size+Vector3.new(10, 10, 10)
		end
	wait(1)
	debounce = false
	end
end

I can use the tool just once, then the debounce go infi.I think it's because x is true yet, even tho it should last 10 seconds.
