Trying to make an ice move, where an ice cylinder spawns, why isn't it spawning?

plar = game.Players.LocalPlayer
Mouse = plar:GetMouse()
char = plar.Character
function press(key)
	key = key:lower() 
	if key == "T" then
		local I = Instance.new("Part")
		I.Material = "Ice"
		I.BrickColor = BrickColor.new("Medium blue")
		I.BottomSurface = "Smooth"
		I.TopSurface = "Smooth"
		I.Shape = "Cylinder"
		I.Size = Vector3.new(25, 1, 2)
		I.CFrame = char.Torso.CFrame.lookVector
		I.Parent = workspace
		local BV = Instance.new("BodyVelocity")
		BV.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
		BV.Velocity = char.Torso.CFrame.lookVector * 40
		BV.Parent = I
		wait(10)
		I:Remove()
	end
end

Mouse.KeyDown:connect(press)

It's meant to spawn a block, but it isn't, why?
