Complicated to fit into a title. Help?

Okay, the title has nothing to do with the thing I want to fix.

What I want to do is to carry the script on without stopping it at my function add60() Since it is a loop. It won't carry on until it finishes, is there a way to bypass this?

Script:

Temperature=game.Workspace.TemperatureValue
ReactorSafeguards=game.Workspace.ReactorSafeguards
ReactorMeltdownSong=game.Workspace.ReactorMeltdownSong
EmergencyPower=game.Workspace.EmergencyPower
EL1=game.Workspace.ELS.EL1.Toggle
EL2=game.Workspace.ELS.EL2.Toggle

function shake()
	local camera = game.Workspace.CurrentCamera
	for i = 1,10000 do	
		wait()
		camera.CoordinateFrame = camera.CoordinateFrame * CFrame.new(0,2,0)
		wait()
		camera.CoordinateFrame = camera.CoordinateFrame * CFrame.new(0,-2,0)
	end 
end 

function add60()
	for i=1, 10 do  -- THIS IS THE FUNCTION WHAT LOOPS
		wait(2)
		script.Parent.TemperatureValue.Value = script.Parent.TemperatureValue.Value +60
	end
	end


while true do
	wait()
if Temperature.Value >= 2000 then
    Temperature.Value = 2001
add60() -- IT STOPS HERE UNTIL IT HAS FINISHED.
	ReactorSafeguards:Play()
	wait(2)
	ReactorMeltdownSong:Play()
	wait(4)
	ReactorSafeguards:Play()
	shake()
	wait(9)
    EmergencyPower:Play()
	wait(1)
	EL1.Value = true
	EL2.Value = true
	break
end
end
