(Edit) Why isn't the explosion appearing?

This script essentially generates an orb, and shoots in out where your mouse cursor is, it will then blow up. Everything is working well, except for the explosion. It wont appear.

I have absolutely NO clue as to why its

game.ReplicatedStorage.Moves.OnServerEvent:Connect(function(plr,mousehit,key)
    if key == "Shakkahou" then
        local char = plr.Character
        local hum = char.Humanoid
        local root = char.HumanoidRootPart
        local charging = Instance.new("Part")
        charging.Size = Vector3.new(1,1,1)
        charging.Transparency = 0.5
        charging.CanCollide = false
        charging.BrickColor = BrickColor.new("Really red")
        charging.Shape = Enum.PartType.Ball
        charging.Material = Enum.Material.Neon
        charging.Parent = workspace
local weld = Instance.new("Weld")
    charging.CFrame = root.CFrame * CFrame.new(0,1.3,-2)
    weld.Part0 = root
    weld.Part1 = charging
    weld.C0 = root.CFrame:Inverse()
    weld.C1 = charging.CFrame:Inverse()
    weld.Parent = charging
    wait(1)
    weld:Destroy()
    local bv = Instance.new("BodyVelocity")
    bv.Parent = charging
    bv.MaxForce = Vector3.new(1e8,1e8,1e8)
    bv.Velocity = mousehit.lookVector*50 
    game.Debris:AddItem(charging,5)
    local debounce = false
    charging.Touched:Connect(function(hit)
        if debounce == false then
        debounce = true
        local ehum = hit.Parent:FindFirstChild("Humanoid") or hit.Parent.Parent:findFirstChild("Humanoid")
        if ehum and ehum ~= hum then
            ehum:TakeDamage(10)
        end
        local explosion = Instance.new("Part",workspace)
        explosion.Size = Vector3.new(1,1,1)
        explosion.Transparency = 0.5
        explosion.CanCollide = false
        explosion.Name = "Explosion"
        explosion.BrickColor = BrickColor.new("Really red")
        explosion.Shape = Enum.PartType.Ball
        explosion.Material = Enum.Material.Neon
        explosion.Position = CFrame.new(charging.CFrame.x,mousehit.y,charging.CFrame.z) 
        local tween = game:GetService("TweenService")
        local tweeninfo = TweenInfo.new(2,Enum.EasingStyle.Quint,Enum.EasingDirection.In,0,false,0)
        local tweenproperties = {Size = Vector3.new(50,50,50)}
        tween:Create(explosion,tweeninfo,tweenproperties)
        wait(2)
        local tweeninfo2 = TweenInfo.new(1,Enum.EasingStyle.Quint,Enum.EasingDirection.In,0,false,0)
        local tweenproperties2 = {Transparency = 1,Size = Vector3.new(40,40,40)}
        tween:Create(explosion,tweeninfo2,tweenproperties2)
        wait(1)
        explosion:Destroy()
        wait(5)
        debounce = false
        end
        end)
    end
