Wtf episode 6

Ok i just started this show and im really enjoying it hope it does get better though i mean it has an 8.5. What im really puzzled about is the powerplant thing hoe did he stop it from exploding? I mean it really looks like some lame oh whatever he just pulled it off ending are we just supposed to buy that or did i miss something vital? If youre gonna spoil me with the answer than dont haha but yeahh thanx in advance apart from that vash is a complete badass and this show is epic
