Why is my debounce variable not working?

I'm making a dynamite tool, but for some reason the debounce doesn't work and you can spam click to spawn more dynamite. Any fixes?

local Tool = script.Parent
local Handle = Tool:WaitForChild("Handle")
local Debounce = true
Tool.Activated:Connect(function()
	if Debounce == true then
		PlantBomb()
		Debounce = false
		wait(3)
		Debounce = true
	end
end)

function PlantBomb()
	local Bomb = Handle:Clone()
	Bomb.Parent = workspace
	Bomb.CanCollide = true
	Bomb.Anchored = false
	Bomb.Transparency = 0
	wait(3)
	local Boom = Instance.new("Explosion")
	Boom.Parent = workspace
	Boom.Position = Bomb.Position
	Boom.BlastRadius = 16
	Bomb:Destroy()
end

Put the debounce changer at the start. As it calls the function then changes the debounce. It needs to change the debounce then call the function.

local Debounce = false —Debounce should always be set to false, not true.
Tool.Activated:Connect(function()
    if Debounce == false then
        Debounce = true
        PlantBomb()
        wait(3)
        Debounce = false
    end
end)
