Fix this script to un-equip once activated...?

So I'm having trouble making this lucky block script un-equip once you use it. So what happens is once you use the lucky block, it deletes the current gears, gives a random, and automatically equips it. The problem is, you have to re-equip the gear, and this is a bit troublesome to the new players as they don't know what to do...

TL;DR Can someone fix it to where it will un-equip then re-equip once "activated"

local Tool = script.Parent

local gears = {173755801, 169669671, 220288991, 170897263, 98253592, 12547976, 45201977, 78730532}

function onActivated()
 -- play sound
    magicSound = Tool.Handle:FindFirstChild("MagicSound")
    if magicSound == nil then return end
    magicSound:Play()

-- GOOD RANDOMIZATION CODE!!
    numLoops = math.random(0,math.floor(1000*time()))
    numLoops = numLoops - (math.floor(numLoops / 10000)*10000)
    for i = 1,numLoops do
        whichNum = math.random(1,#gears)
    end
-- END OF GOOD RANDOMIZATION CODE!

    print("Picked: ")
    print(whichNum)
    local root = game:GetService("InsertService"):LoadAsset(gears[whichNum])

    local instances = root:GetChildren()
    if #instances == 0 then
        root:Remove()
        return
    end

    root = root:GetChildren()
    if #root == 1 then
        root = root[1]
    else return end
    print(root)
    root.Parent = Tool.Parent
    Tool:remove()
end

function onEquipped()
    magicSound = Tool.Handle:FindFirstChild("MagicSound")
    if magicSound == nil then
        magicSound = Instance.new("Sound")
        magicSound.Parent = Tool.Handle
        magicSound.Volume = 1
        magicSound.SoundId = "http://www.roblox.com/asset/?id=144007386"
        magicSound.Name = "MagicSound"
    end
end

Tool.Activated:connect(onActivated)
Tool.Equipped:connect(onEquipped)
