Why isnt my ball showing up in the player's hand?

I made this script when the player is holding a tool and clicks it starts an animation and a ball of lightning appears on his arm. The animation works fine but the ball only shows up at all. here is the script

tool = script.Parent

replicatedstorage = game:GetService("ReplicatedStorage")
staticball = replicatedstorage.RicoClass:findFirstChild("Lightning")


tool.Selected:connect(function(mouse)
	mouse.Button1Down:connect(function()
	local player = game.Players.LocalPlayer
	local Humanoid = player.Character.Humanoid
---------------------------------------------------------------------------------
		local Punch = Instance.new("Animation")
		Punch.AnimationId = "http://www.roblox.com/Asset?ID=644505212"
		local animTrack = Humanoid:LoadAnimation(Punch)	
			animTrack:Play(0,2,2.5)
---------------------------------------------------------------------------------			
    local light = replicatedstorage.RicoClass:WaitForChild("Lightning")
	light:clone()
		
		light.Parent = player.Character
		light.Anchored = false
		light.CanCollide = false
		local w = Instance.new("Weld" ,light)
		w.Part0 = player.Character.RTIndexFinger
		w.Part1 = light
		w.C1 = CFrame.Angles(0,0,40)
		w.C0 = CFrame.new(0,0,0.2)
			
		
	end)
	
	
	
end)
