Block Penetration

{SKILL LEVEL ONE - See "Skill Levels" at left}

A cylinder with a closed end and a block, both with holes through them, are locked with a steel rod passing through the holes. The block instantly penetrates the rod. You get a plastic cylinder (1" diameter and 2" long), block (7/8" diameter and 1" long) and a 3-1/2" long steel rod with complete instructions.
