Corrected entry: While Clark is inside the semi-truck being delivered to Morgan Edge and Lionel Luthor he manages to remove the kryponite apparently duct taped to his chest. This cannot be possible since he even a small piece of kryptonite (Lana's necklace) was enough for him to trip and fall from several feet away! Imagine a larger chunk like the one they strapped to his chest. He should have been severely weakened by it and the radiation should go through anything in that truck besides lead and the tape used to secure the rock on Clark's chest is not made of lead. His ability to not only have the strength to rip the taped rock off his chest but to then launch it to the far side of the truck should not be possible in view of the nearly immobilizing effects kryptonite has on Clark.
