Help with BodyVelocity?

I want to launch this fireball up to the sky. I've tried to play around with the numbers of Bodyvelocity but didn't work.Any suggestions?

Player = script.Parent.Parent.Parent
n = script.Parent
local debounce = false
mouse = Player:GetMouse()
run = game:GetService("RunService")
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 = 0.2
			x.Parent = Workspace
			x.Size = Vector3.new(10, 50, 10)
			x.BrickColor = BrickColor.new("Brown")
			x.Name = Player.Name
			y = Instance.new("BodyVelocity")
			y.maxForce = Vector3.new(0, math.huge, 0)
			y.velocity = Player.Character.Torso.CFrame.lookVector*110
			x.Parent = Workspace
			y.Parent = x
			x.CFrame = Player.Character.Torso.CFrame*CFrame.new(0, 0, -10)
			game.Debris:AddItem(x, 10)

	end
	wait(35)
	debounce = false
end




function onSelected(mouse)
	mouse.Button1Down:connect(function() pizza(mouse) end)
end

n.Selected:connect(onSelected)
		

For the velocity set it to: (Player.Character.Torso.CFrame.lookVector*110).unit
