Why doesn't the blast move?

I've created a script where when you press q, you create a blast or whatever. My point is, the thing doesn't move when you press q.

So it just sits there. Image: https://gyazo.com/06c5ba2c451f785d3a8bdd2e6d986e1b

My script:

player = game.Players.LocalPlayer
mouse = player:GetMouse()
mouse.KeyDown:connect(function(key)
	key = key:lower()
	if key == "q" then
			if player.DevilFruit.Value == "Smoke" then
				for i = 1,1 do -- i know i dont need this here
					game:GetService("Chat"):Chat(player.Character.Head, "SmokeySmoke!11")
					f=Instance.new("Part", game.Workspace)
					f.Size = Vector3.new(23,23,23)
					f.Anchored = false
					f.BrickColor = BrickColor.new("White")
					f.Transparency = 0.3
					f.Name = "Smokepush"
					f.TopSurface = "Smooth"
					f.BottomSurface = "Smooth"
					f.CanCollide = false
					f.CFrame = player.Character.Torso.CFrame * CFrame.new(0,0,-5+-i)
					local ow = Instance.new("StringValue", f)
					ow.Name = "Owner"
					ow.Value = player.Name
					local fi = Instance.new("Smoke", f)
					fi.Size = 10
					fi.RiseVelocity = 25
					fi.Opacity = 1
					fi.Enabled = true
					--game.ReplicatedStorage.MeraDmg2:Clone().Parent = f
					local y = Instance.new("BodyVelocity", f)
					y.maxForce = Vector3.new(math.huge,math.huge,math.huge)
					y.velocity = player.Character.Torso.CFrame.lookVector*80
				end
		end	
	end
end)
