Is there anyway I can make this script make a tool unable to be picked up?

This is a script I use for a landmine, but after about a second of deploying it's still able to be picked up.

function drop()
    script.Parent.Parent = game.Workspace
    script.Parent.Handle.CFrame = script.Parent.Handle.CFrame + Vector3.new(0,-1,0)
    local rotation = CFrame.Angles(0,180,-90)
    script.Parent.Handle.CFrame = rotation + script.Parent.Handle.Position
    script.Parent.Handle.Name = ("Explode")
    wait (2)
    script.Parent.Explode.Explode.Disabled = false
end

script.Parent.Activated:connect(drop)

Is there anyway I can edit this script so the landmine can't be picked up?
