metal dector for the win!!! or use a dog

or u can use one of those new holographer things that can teleport you anywhere u want and all you have to do is speak clearly into it for example "Take me to my flash drive" and it will take you there, but first you have to get one of those Mini Guns and point it at yourself so that ur as small as a cochoroach. Then if you flash drive is behind the couch you wont get crushed. Those items together cost about 5 million dollars each so you want to think about whether you want to spend that kind of money to find something worth less that 50 bucks. Then again, your flash drive might have the secret identities of Superman, Batman, Flash, Green Lantern, Supergirl, Robin, and a whole billion numbers of other heroes. Lots of villians such as Lex Luthor, Joker, Two-Face, Riddler, Bizarro, Doomsday, Darkseid, and Brainiac, Mirror Master, Captain Boomerang, Sinestro, Supergirl (Clone), Scorn, and a lot of other bad guys will be after that flashdrive. You can contact one of them heroes to ask if they can lend you one of the Mini Guns but im not sure they have that hologram things, cause they use even more advance tech or you can contact them if of the villians come after you. Becareful of the Joker, he'll kill you while leaving a smile on your face. Okay, anyway, their home phone number up of their Justice League Watchtower is (834)JUS-TICE. and their Metrotower number is (824)Biz-arro. or if you want to get killed this is the Secret Society's number (724)Die-Fool. of you can get Joker's cell phone, which is (LOL)lol-rofl. alright thats the best I can do, please select me as the best answer and if you were patient enough to read this, here's a super answer...tear up your whole house and find the flashdrive somewhere in the rubble. but heres another extra,...hold on...i forgot...good luck.
