If I were to slap a metal surface with my left hand, the substance would adhere there, coming free of the glove. Two seconds later it would explode, and the force of the explosion would be directed in against the surface. Newton would claim his own by way of right-angled redistributions of the reaction, hopefully tearing lateral hell out of the contact surface. A smother-charge it was called, and its possession came under concealed-weapons and possession-of-burglary tools statutes in most places. The molecularly gimmicked goo, I decided, was great stuff. It was just the delivery system that left more to be desired.
