I am making a Kamehameha, for some reason, randomly, the loop will make it drift off to the side. I have no idea how to fix it.

(For people who want to see it for themselves I edited the script to work with an Instance.new)

function kame(player, localplayer, character, size)
	local length = 5 -- This will be the length of the attack
	local place = 5 -- The offset for how far ahead the attack will be
	local noMove = length / 2 -- Don't touch this 
	local atkTime = 0.1 -- The rate at which the attack dissapates
	local transRemove = 0.1 -- The rate at which transperancy increases
	local wave = Instance.new("Part")
	local torso = localplayer.Character.UpperTorso
	wave.CFrame = torso.CFrame + torso.CFrame.lookVector * place
	wave.Orientation = wave.Orientation + Vector3.new(90, 0, 0)
	wave.Size = wave.Size + Vector3.new(size, 0, size)
	wave.Anchored = true
	wave.CanCollide = False
	wave.Parent = game.Workspace	
	for i = 20, -100, -1 do -- Problem Area
		wait(0.1)
		print("working")
		place = place + noMove
		wave.Size = wave.Size + Vector3.new(0, length, 0)
		wave.CFrame = torso.CFrame + torso.CFrame.lookVector * place
		wave.Orientation = wave.Orientation + Vector3.new(90, 0, 0)
		if i < 11 then
			wave.Transparency = wave.Transparency + transRemove
		end
		if wave.Transparency > 1 then
			wave:Destroy()
			break
		end
	end
	for i=1, #character do
   		if character[i].ClassName == "Part" then
      	character[i].Anchored = false
   	 	end
	end	
	localplayer.Character.Humanoid.WalkSpeed = 16
	localplayer.Character.Humanoid.JumpPower = 50
end

The script is supposed to just make it appear directly in front of me and expand forwards, but sometimes it veers to the side.
