Why won't this script make 2 parts explode?

Well, this is kind of a remix from my other question. My problem is, why won't this make 2 explosion parts explode?

while true do
	local expParts = script.Parent.ExplosionParts:GetChildren()
	local number = math.random(1, #expParts)
	local number2 = math.random(1, #expParts)
	local explosionPart2 = expParts[number2]
	local explosionPart = expParts[number]
	local script = game.Lighting.Script:Clone()
	local script2 = game.Lighting.Script:Clone()
	wait(0.5)
	local explosion = Instance.new("Explosion")
	explosion.BlastRadius = 25
	explosion.BlastPressure = 250000
	explosion.ExplosionType = Enum.ExplosionType.CratersAndDebris
	explosion.Parent = workspace
	explosion.Position = explosionPart.Position
	script.Parent = explosion
	local explosion2 = Instance.new("Explosion")
	explosion2.BlastRadius = 25
	explosion2.BlastPressure = 250000
	explosion2.ExplosionType = Enum.ExplosionType.CratersAndDebris
	explosion2.Parent = workspace
	explosion2.Position = explosionPart2.Position
	script2.Parent = explosion
end
