How to make parts disappear after some time

[LENISLAVV]

Hey! I’m pretty new to scripting, and I found this simple script for my build, but I want the parts to disappear after some time, everything I tried makes it so the part spawns 5 seconds after the other, but I want them to spawn continuously, and after some time they’ll disappear. Thanks!
Here’s the script:

local shapes = {
	Enum.PartType.Ball,
	Enum.PartType.Cylinder,
	Enum.PartType.CornerWedge,
	Enum.PartType.Block,
	Enum.PartType.Wedge,
}

while wait() do
	
	local thing = Instance.new("Part",game.Workspace)
	thing.Position = script.Parent.Position
	thing.BrickColor = BrickColor.random()
	thing.Shape = shapes[math.random(1,#shapes)]
	thing.Size = Vector3.new(1,1,1)
	
end

To make something disappear after some time, you can use Debris

[09glich2 (09glich)]

To put it simple

local Debris = game:GetService("Debris")
Debris:AddItem(Item, Time) -- Simple way

this will simply make it pop out of existence after the amount of time you give it. fair warning it requires seconds.
