I am trying to create a light beam in a tool. Other people cant see it in the game?? help

Help me here is the Local Script:

 local Tool = script.Parent
 local player = game:GetService("Players").LocalPlayer

 local en = true
Tool.Equipped:connect(function(mouse)
print("Tool equipped!")
if not en then return end
 en = false
Tool.RemoteEvent:FireServer(mouse.Hit)
wait(.5)
en = true
	
mouse.Button1Down:connect(function()
	print("Mouse pressed!")
	local ray = Ray.new(Tool.Handle.CFrame.p, (mouse.Hit.p - Tool.Handle.CFrame.p).unit * 300)
	local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)

	local beam = Instance.new("Part", workspace)
	beam.BrickColor = BrickColor.new("New Yeller")
	beam.FormFactor = "Custom"
	beam.Material = "Neon"
	beam.Transparency = 0.25
	beam.Anchored = true
	beam.Locked = true
	beam.CanCollide = false

	local distance = (Tool.Handle.CFrame.p - position).magnitude
	beam.Size = Vector3.new(.5, .5, distance)
	beam.CFrame = CFrame.new(Tool.Handle.CFrame.p, position) * CFrame.new(0, 0, 	-distance / 2)

	game:GetService("Debris"):AddItem(beam, 1)

	if part then
		local humanoid = part.Parent:FindFirstChild("Humanoid")

		if not humanoid then
			humanoid = part.Parent.Parent:FindFirstChild("Humanoid")
		end

		if humanoid then
			humanoid:TakeDamage(30)
		end
	end
	beam.Touched:Connect(function(hit)
		if not en then return end
 en = false

		for i = 1,10 do
			local Explosion = Instance.new("Part")
			Explosion.BrickColor = BrickColor.new("New Yeller")
			Explosion.Shape = Enum.PartType.Ball
			Explosion.Material = "Neon"
			Explosion.FormFactor = "Custom"
			Explosion.Transparency = 0.25
			Explosion.Size = Vector3.new(50,50,50)
			Explosion.CanCollide = false
			Explosion.Anchored = true
			Explosion.Locked = true
			Explosion.CFrame = beam.CFrame
			Explosion.Parent = game.Workspace
			game.Debris:AddItem(Explosion,1)
			wait(0.005)
			Explosion.Size = Vector3.new(55,55,55)
			wait(0.005)
			Explosion.Size = Vector3.new(58,58,58)
			wait(0.005)
			Explosion.Size = Vector3.new(60,60,60)
			wait(0.005)
			Explosion.Size = Vector3.new(65,65,65)
			wait(0.005)
			Explosion.Size = Vector3.new(70,70,70)
			wait(0.005)
			Explosion.Size = Vector3.new(75,75,75)
			
			
			wait()
			en = true
			
		end
		
	end)
end)
end)

I have a remote event in the tool too. its kind of based off of kizaru's finger blast. Appreciated.
