When I clone a part that has a script in it the script doesn't activate?

I'm working on a script where a sphere expands then disappears and it works perfectly when tested in the workspace but the instant I clone it it no longer activates the script. I've attempted deactivating then activating it with a script once it gets added to the workspace but that didn't work either. Any help would be much appreciated thanks.

Grow = script.Parent

magicgrowth = coroutine.wrap(function()
    for i = 1,20 do
        Grow.Size = Grow.Size + Vector3.new(.5,.5,.5)
        wait(.1)
    end
end)

trans = coroutine.wrap(function()
    for i = 1, 20 do
        Grow.Transparency = Grow.Transparency + 0.05
        print("why")
        wait(.1)
    end
end)
coldweather = coroutine.wrap(function()
    for i = 1, 20 do
        Grow.Size = Grow.Size - Vector3.new(.5,.5,.5)
        wait(.1)
    end
end)

trans()
magicgrowth()
wait(3)
coldweather()
wait(2)
Grow:Destroy()
