Making a droppers brick disappear after 10 seconds??? For tycoon

You can make it automatically disappear after 10 seconds using the Debris Service:

local deb = game:GetService("Debris")

function fire()
    local p = Instance.new("Part")
    p.Position = script.Parent.Position
    p.Size = Vector3.new(1,1,1)
    p.BrickColor = BrickColor.new(106) 
    p.BottomSurface = 0
    p.TopSurface = 0
    p.Name = "TycoonBrick" 
    p.Parent = script.Parent
    deb:AddItem(p, 10) -- This is the only change necessary.
end 


while true do
    wait(2.5) --Alter Rate Of Drop
    fire()
end

If the Part it already gone (Destroyed or otherwise) when Debris is told to remove it, very simply nothing happens.
