How do to destroy instances?

Ive tried to create a lag test game for roblox but im struggling to destroy once its been created, ive tried everything but it still wont work

Heres the code:

"wait(0.0000001) local LagPart1 = Instance.new("Part") LagPart1.BrickColor = BrickColor.new("Institutional white") LagPart1.Material = ("ForceField") LagPart1.Parent = game.Workspace LagPart1.Position = Vector3.new(12, 61.5, 5) LagPart1.Name = "LagParts" LagPart1.Size = Vector3.new(6,6,6)"

"Reset.MouseButton1Up:Connect(function() Reset1 = true workspace:WaitForChild(LagPart1):Destroy()

end)"

If you really wants to wait for a zeptosecond or the minimum second, consider changing to wait(). It takes 0.0002 seconds (I'm not sure I heard someone say it is)

You can clone an model and store all the parts inside, when you want to destroy all, destroy the model. It will be easier and straightforward.
