Trying to spawn a bunch of parts over the map not working?

I made a script that is supposed to just spawn parts all over the map but it isn't working and there are no errors.

My script (server side script)

for i = 1,100 do
    local part = Instance.new('Part')
    part.Anchored = false
    part.CanCollide = true
    part.Position = Vector3.new(math.random(-100,100),math.random(-100,100),math.random(-100,100))
    wait()
end
