Reminds me of trying to cheat myself in 70's by making a lead conker (painted to be right color). It got confiscated at school as being dangerous (lump of lead on a string) before I could even use it. Conkers is half about cheating anyway - baking it to make it rock hard, or soaking in vinegar to make it rubbery and resilient.
