[SOLVED]Why is it not doing in pairs but just part for part? No errors

i did this but i does part for part not at the same time?

while true do
	for i,v in pairs(script.Parent.Kant:GetChildren()) do
		print(v)
		v.Material = "Neon"
		v.BrickColor = BrickColor.new("Deep blue")
		v.PointLight.Enabled = true
		wait(0.2)
		v.Material = "Glass"
		v.BrickColor = BrickColor.new("Bright blue")
		v.PointLight.Enabled = false
	end
	wait(0.2)
	for i,v in pairs(script.Parent.Kant2:GetChildren()) do
		v.Material = "Neon"
		v.BrickColor = BrickColor.new("Deep blue")
		v.PointLight.Enabled = true
		wait(0.2)
		v.Material = "Glass"
		v.BrickColor = BrickColor.new("Bright blue")
		v.PointLight.Enabled = false
	end
end

For In Pairs loop does not loop them all at the same time, it loops it through then goes to the next one. If you want them to all loop at once use the spawn() function.

while true do
    for i,v in pairs(script.Parent.Kant:GetChildren()) do
    	spawn(function()
	        print(v)
	        v.Material = "Neon"
	        v.BrickColor = BrickColor.new("Deep blue")
	        v.PointLight.Enabled = true
	        wait(0.2)
	        v.Material = "Glass"
	        v.BrickColor = BrickColor.new("Bright blue")
	        v.PointLight.Enabled = false
    	end)
    end
    wait(0.2)
    for i,v in pairs(script.Parent.Kant2:GetChildren()) do
    	spawn(function()
	        v.Material = "Neon"
	        v.BrickColor = BrickColor.new("Deep blue")
	        v.PointLight.Enabled = true
	        wait(0.2)
	        v.Material = "Glass"
	        v.BrickColor = BrickColor.new("Bright blue")
	        v.PointLight.Enabled = false
    	end)
    end
end
