Executing Function for second time doesn't work?

This script works but when it does once again it doesn't in the same Roblox studio play session.

For example the Scale of the mesh normally is (5,7,5) then when its back to (5,7,5) it doesn't work anymore...

I've tried adding if-repeat-then and many more and doesn't work (maybe) in the way i did.

local Ice = script.Parent
local t = 2

wait(t)
Ice.Mesh.Scale = Vector3.new(4.5,6.5,4.5)
wait(t)
Ice.Mesh.Scale = Vector3.new(4,6,4)
wait(t)
Ice.Mesh.Scale = Vector3.new(3.5,5.5,3.5)
wait(t)
Ice.Mesh.Scale = Vector3.new(3,5,3)
wait(t)
Ice.Mesh.Scale = Vector3.new(2.5,4.5,2.5)
wait(t)
Ice.Mesh.Scale = Vector3.new(2,4,2)
wait(t)
Ice.Mesh.Scale = Vector3.new(1.5,2.5,1.5)
wait(t)
Ice.Mesh.Scale = Vector3.new(1,2,1)
wait(t)
Ice.Mesh.Scale = Vector3.new(0.6,1.2,0.6)
Ice.CanCollide = false

Oh boy I know this isnt an answer, but I just cant stand seeing this

Ice = script.Parent
function MoveIce()
for i = 1,9 do -- change the 9 to whatever (how far it goes)
wait(2)
Ice.Mesh.Scale.CFrame = Ice.Mesh.Scale.CFrame - Vector3new(.5, .5, .5)
end
Ice.CanCollide = false
end

MoveIce()
