Minato88 your normally more reasonable so I'll put this forth so you can see why it doesn't make sense. how can he be entirely correct about Rukia giving her power to Ichigo being something the Hogyoku did when she wasn't in-planted with the Hogyoku until after she had given her power to Ichigo. She hadn't come into contact with Urahara until after that had taken place and she was powerless. This is even brought up by Aizen in the SS arc.

Also as i stated before why hide or try to destroy something if he didn't know what it was capable of. Note he never says that breaking down the shinigami and hollow barriers is all it can do, just that it can save shinji and the others and that he created the substance while doing research into "strengthening souls". Why and for what purpose he would research that is never explained. He did what he did for the Vizard and though he views it as a failure he apparently succeeded. As Lia previously said Urahara even stated he didn't miscalculate as that was his only miscalculation, that it everything happened as expected the worst way. Urahara has definitely omitted alot of information its time he explains.
