You have to do well on the math tests on Friday a few times and then you get a new perk. Then go to Alice's house at night and talk to her, there's an option about creating stuff, two things. One of those is the x-ray glasses. You can buy the mats for it, or you can find them around the game. if you want to buy the mat's for both, it's going to be like $150 I think total. Don't remember, but it's a decent chunk of change.How do you get the x-ray glasses?
