My Ice block does damage now, however it doesn't even spawn in online, any idea why?

local plar = game.Players.LocalPlayer
local Mouse = plar:GetMouse()
local char = plar.Character
local charge = 0
function press(key)
	if charge >= 2 then return
		end
	key = key:lower() 
	if key == "t" then
		charge = charge + 1
		local I = Instance.new("Part")
		I.Material = "Ice"
		I.BrickColor = BrickColor.new("Medium blue")
		I.BottomSurface = "Smooth"
		I.TopSurface = "Smooth"
		I.Shape = "Cylinder"
		I.Size = Vector3.new(25, 1, 2)
		I.Transparency = .4
		I.CFrame = char.Torso.CFrame * CFrame.new(0, 0, -10)
		I.Parent = workspace
		I.Touched:connect(function(char)
			if char.Parent:FindFirstChild("Humanoid")~= nil then
				char.Parent:FindFirstChild("Humanoid").Health = char.Parent:FindFirstChild("Humanoid").Health - 5
			end
		end)
		local BV = Instance.new("BodyVelocity")
		BV.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
		BV.Velocity = char.Torso.CFrame.lookVector * 40
		BV.Parent = I
		for c = 1,90 do
			I.CFrame = I.CFrame * CFrame.fromEulerAnglesXYZ(0, .3, 0)
			wait(.03)
			end
		I:Remove()
		charge = charge - 1
		end
end
Mouse.KeyDown:connect(press)

help.
