what has simon been up to i havent seen him respond to any sugesstions lateley like this one i would LOVE to hear his opinion bout [LEAD] absorbs neutron melts poisononous to stickman dense ( if powder) hmm that might work!
I support this idea too, except the indestructability part. I think LEAD should have a low-ish melting point and turn into LLED (liquid lead) instead of LAVA.
