Prints twice even with debounce?

So even with a debounce on my explosion part script, i added a print statement to see how many times it explodes. When i run it and touch the part, it prints multiple times, even with the debounce. Any reasons?

local debounce = false
script.Parent.Anchored = true
script.Parent.Position = Vector3.new(3,0.5,3)

script.Parent.Touched:Connect(function(hit)
    if debounce == false and hit.Parent:FindFirstChild("HumanoidRootPart")
    then
        debounce = true
        local explosion = Instance.new("Explosion")
        script.Parent.BrickColor = BrickColor.new("Really red")
    explosion.Position = hit.Parent:FindFirstChild("HumanoidRootPart").Position
    explosion.Parent = hit.Parent:FindFirstChild("HumanoidRootPart")
    game.Workspace.Part.pow:Play()
    print("Explosion")
    end
    wait(10)
    debounce = false
    script.Parent.BrickColor = BrickColor.new("Medium stone grey")
end)
