How do I get my code to repeat explosions?

I used a piece of code from another question here so I could make explosive bricks, but I modified it and cant seem to get it to constantly repeat explosions.

local currentlyDelaying = false -- Don't touch this.
	if currentlyDelaying == false then
		repeat
	        local exp = Instance.new("Explosion", script.Parent)
	        exp.BlastPressure = 750000 -- The pressure of the explosion
	        exp.BlastRadius = 5 -- The radius of the explosion
	        exp.DestroyJointRadiusPercent = 400 -- The radius of where joints are destroyed upon impact
	        exp.ExplosionType = Enum.ExplosionType.Craters -- What type of explosion do you want? Craters, CratersAndDebris, or NoCraters.
	        exp.Position = script.Parent.Position -- The position of the explosion
	        exp.Visible = false -- If the explosion can be seen
			wait(0.1)
until		wait(10)
		script.Parent:Destroy()
	end

instead of repeat, put while true do.
