I need help to make a brick that regens after 5 secs

Engine = script.Parent.Parent.Engine
Wing1 = script.Parent.Parent.Wing1
BrickToHide = script.Parent

local function hideBrickFor5Seconds(brick)
	brick.Transparency = 1
	delay(5, function()
		brick.Transparency = 0
	end)
end

local activated = false --debounce to prevent activating repeatedly
function onTouched(hit)
	local human = hit.Parent:findFirstChild("Humanoid")
	if human and not activated then
		activated = true
		hideBrickFor5Seconds(BrickToHide) --If you want the block to be hidden BEFORE the engine and wings move, leave this here
		for loop = 1, 100 do
			Engine.CFrame = Engine. CFrame *CFrame.new(0, 0, -.1) -- z makes it move forwad
			wait(1/25)
			Wing1.CFrame = Wing1.CFrame *CFrame.new(0, 0, .1)
			wait(1/25)
		end
		--hideBrickFor5Seconds(BrickToHide) --If you want the block to be hidden AFTER the engine and wings move, uncomment this line
		activated = false
	end
end
script.Parent.Touched:connect(onTouched)
